Top 3 questions answers- 1) The acid needed here is Nitric acid and the base needed here is Ammonium hydroxide. The chemical reaction is- HNO3 + NH4OH = NH4NO3 + H2O. 2) a) Vinegar contains acetic acid. b) Milk contains lactic acid. c) Tomatoes contain oxalic acid. d) Apples contain malic acid. 3) Toothpaste is basic in nature. Our mouth contains many acids. We know that a base can neutralize an acid. In this case it becomes neutral and that's why Toothpaste help prevent decay teeth. And another acid that tomatoes contain I think other than oxalic acid is citric acid since it is sour. Sir would you please check my answers?
1. Ammonium chloride(weak base)+ Nitric acid (strong acid)will give Ammonium nitrate(acidic salt)+ water. 2.(a)Acetic Acid,(b)Lactic Acid,(c)Oxalic Acid,(d)Malic Acid. 3.Toothpaste is actually basic in nature. So, it helps in removing the bacteria that is present in the teeth that contains acid. So, the toothpaste will neutralise the acid and helps in preventing tooth decay.

Tomato sauce has vinegar in it which is used in many materials like pickles as a preservative. Thus, tomato sauce has oxalic and acetic acid. 1.) Ammonium Hydroxide + Nitric Acid ----------> Ammonium Nitrate + Water + Heat NH4OH + HNO3 ---------> NH4NO3 + H2O + Q 2.) a.) Vinegar isused in many materials like pickles as a preservative and has Acetic acid in it. b.) Milk or curd has lactic acid in it c.) Tomato sauce has Oxalic acid present in it d.) Apples is mostly determined by the Malic acid present in it 3.) Major tooth issues like tooth decay is caused when we eat sugary foor such as chocolates, sweets, etc. The bacteria's act upon this sugar and transform it into acid because ( bacteria + sugar = acid ), and this acid eats up the tooth leading to tooth decay. As Toothpaste is a base, it prevents the acid from eating up the tooth by neutralizing it's effect. Hence, Toothpaste prevents tooth decay
1.Answer. nitric acidThe industrial production of ammonium nitrate entails the acid-base reaction of ammonia with nitric acid: HNO3 + NH3 → NH4NO. Ammonia is used in its anhydrous form (a gas) and the nitric acid is concentrated. The reaction is violent owing to its highly exothermic nature. 2.a)vinegar-acetic acid b) milk-lactic acid c)tomatoes-oxalic acid d) apple- malic acid 3.Toothpastes are basic in nature. They neutralise the effect of acids and thus prevent tooth from decaying.
1..HNO3+NH4OH---- NH4(NO3) 2.vinegar-acetic acid Milk-lactic acid Tomatoes-oxalic acid Apple-malic acid 3.tooth paste(base) helps in avoid decaying of enamel of teeth as the microbes in our mouth produces acid which cause decay of enamel,and this base neutralizes acid..
1)HNO3 +NH3 = NH4NO 2) a) vinegar : acetic acid b)milk : lactic acid c)tomatoes : oxalic acid d) apples : malic acid 3)When food particles decay in our teeth , the level of acidity in our mouth rises .This leads to tooth decay. Toothpaste are basic to nature . So, this neutralizes the acids and help prevent tooth decay . Sir very understandable. Please make more videos like this ...
1. Ammonium nitrate (NH4NO3) is indeed soluble in water. It is formed by the reaction between ammonium hydroxide (NH4OH) and nitric acid (HNO3). 2. Vinegar contains acetic acid, milk contains lactic acid, tomatoes contain oxalic acid, and apples contain malic acid. These acids contribute to the characteristic taste of the respective food items. 3. The bacteria living on the teeth and gums produce acid, which can erode the tooth enamel and cause dental decay. Fluorine, which is contained in toothpaste, neutralizes this acid and helps to prevent tooth decay.
In my school my teacher also said this lesson but I didn't understood.But you said so clearly and now I understood this lesson.Thank you very much sir.
1.Ammonium hydroxide+ nitric acid gives Ammonium nitrate and water. NH4OH(aq)+ HNO3(aq) gives NH4NO3 +H2O. 2. Vinegar- Acetic acid, apple- malic acid Milk- lactic acid, Tomatoes- oxalic acid 3. Bacteria present in our mouth break glucose and acid is formed, so; we use toothpaste which contains base that neutralize the acid.

Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay. Are my answers correct sir
tomato sauce has both citric and malic acids . toothpaste contains flouride making it a base and helps to remove tooth decay by neutralising the effect of the acid
Answer 1nitric acid and ammonium hydroxide is used to form salt ammonium nitrate and the chemical reaction is NH4N03+H2O. 2.a.Acetic acid b.Lactic acid c. Oxalic acid d.malic acid 3.Toothpaste which is a base helps prevent tooth decay by neutralizing the excess acid realised by the bacteria present in our mouth.
1) Base is NH3, Acid is HNO3 Chemical reaction:- NH3 + HNO3 ➡️ NH4NO3. 2) (a) vinegar - acetic acid (b) milk- lactic acid (c) tomatoes - oxalic acid (d) apple - malic acid. 3) Fluoride is a compound that is added to toothpaste to reduce decay. Fluoride becomes incorporate into our teeth as they develop and makes them more resistant to decay. -thank you Rishita Nath (class 10)
1.NH4OH+HNO3~NH4NO3+H2O 2.(a) acetic acid (b) lactic acid (c) oxlic acid (d) malic acid 3.when we eat food, food and sugar produces acid. The acid will form in mouth to neutral the mouth from acid we use tooth paste as mild base.
3:) *Tooth decay is caused by the bacteria present in our mouth already, but they inject acids into our teeth spaces when the food we eat gets stuck. So, if a bacterium release acid, toothpaste prevents it because it itself is a base.* Because Acid + Base = Neutrality, *We can say that toothpaste prevents tooth decay.* By the way, well explained Manocha Academy.
1.HCL and NH4OH 2.Vinegar-Acetic acid CH3COOH Milk-Lactic acid C3H6O3 Tomatoes-Oxalic acid Apples-Malic acid 3.It helps to prevent decay of teeth from excess acid in our tooth by neutralizing it.
Since the reaction is between an acid and a base, it should produce salt and water right? Shouldn't the acid be HNO3 and base NH4OH to produce NH4NO3 and H20
NaOH + HNO3. = NH3NO3 +H2O 2 a) acetic acid b) lactic acid c) oxalic acid d)malic acid 3. The food we eat is a acidic one .... It may cause tooth decay. Toothpaste is a base which neutralize
Thank you very much It was very helpful to me. You are teaching I a excellent way that our school teacher are not able to explain like this 👌👌👌👌👌👌👌👌👌👌😃😃😃😃👍👍👍👍👍👍👍👍🙏🙏🙏🙏👍👍👌👌👌
Q.3 Before we brush our teeth the pH of saliva is less than 7 that is acidic. The toothpaste contains the alkali substance which neutralizes the acid and prevent from tooth decay. If you got your answer hit a like!!!👍👍👍👍👍
1)NH4NO3____NH4OH+HNO3 2)vinegar -acetic acid Milk. -lactic acid Tomato - oxalic acid Apple -malic acid 3)Tooth paste contain salt it neutrize acid and base so it help to prevent dacay ofteeth
Hlo sir i'm from Nepal and during the online class my science teacher usually show your videos and it is very helpful to all of us and tomorrow is the turn for this chapter soo i'm looking it before our teacher show us...thanks for the great video sir..please pin my comment so that my teacher will see while showing us tomorrow🙏🙏❤️
2 : a. acetic acid b. Lactic acid c.oxalic acid d. Malic acid 3 : because in toothpaste calcium and phosphate are there to create a strong defense to prevent from cavities
1.NH3+NO3=NH4NO3 2.a)venigar=acetic acid B)Milk=lactic acid C)tomatoes =oxalic acid D)apples=malic acid 3) this is because when we not brush it releases acid and while we are doing brush Toothpaste is base both acid and base becomes neutralize
A:1 HNO3 + NH4OH --> NH4NO3 A:2 a) Acetic Acid b) Oxalic Acid c) Lactic Acid d) Citric Acid A:3 Toothpaste contains base which neutralises the effect of acid present in decay of teeth.
Actually,we eat the food which contains acids and if the acidic nature is more in our teeth it may cause tooth decay so we use the basic paste to neutrilize it
Today is the only day I'm watching you and I saw your previous videos and I'm still wondering why you only have 100k subscriptions you really deserve more than that uncle much love from somalia🖤
@@ManochaAcademy we will be sharing it bkz if only we get the knowledge it's not enough no sir Everyone should be educated no sir Thank you sir for your tremendous teaching
Q1 Acid + Base = Salt + water Let's take given products to determine reactant which are acid and base so by double displacement We get eq NH*4NO*3+ H2O= NH*4OH + HNO *3 Acid is nitric acid and base is ammonium hydroxide Q2. a. Acetic acid b. Lactic acid c. Oxalic acid d. Malic acid Q3. Fluorine is the halogen forming salts used tooth paste so when it combines to phosphorus and calcium present in teeth forms fluorapatite which is crystalline mineral like salt. That fluorine compound prevent us to tooth decay 🇵🇰
When pH value of mouth is below 5.5 bacteria present in mouth produce acid by degration of sugar and food particles remain in the mouth. The best way to prevent this to clean the mouth after eating food. Using toothpaste, which are generally basic neutralize the access acid and prevent tooth decay
Q1)HNO3=acid NH3=base So,HNO3+NH3-----NH4NO3 Q2)a)vinegar-acetic acid b)milk-lactic acid c)Tomato-oxalic acid d)apples-malic acid Q3)Because toothpaste contains fluoride,fluoride fights against the bacteria present in our teeth and helps to prevent the decay in teeth
Sir that was really great even my all the doubts were cleared🙂 your explanation is very good and even you are a great chemistry teacher 👍so can you please make more videos for this lesson please sir🙏🙏
Q3:when we don't wash our mouth after eating food particles settle down in our teeth.Some bacteria grow in that and produces acids. Toothpaste is a base which neutralises the acid and we can prevent tooth decay
The Best explanation. I am in high schol. And this chapter is hard. But you made it easy a ton. Thx soo much . Excorage you to make such videos and I (Subscribed)
How does tooth paste help in tooth decaying answer: - the nature of the toothpaste is alkaline, which is basic . They neutralize the acid produced by bacteria in mouth.

3)when ph of mouth saliva falls below 5.5,the enamel gets weathered. Toothpastes which are generally basic are used for cleaning the teeth that can neutralize the excess acid and prevent tooth decay.
Are my answers correct sir
Thanks for your answers
This helps me alot I have problems in first question but now it is clear
tomato sauce has both citric and malic acids . toothpaste contains flouride making it a base and helps to remove tooth decay by neutralising the effect of the acid
Sir how to remember the activities and how to know which acid is used in particular activity or experiment of chemical science plz reply sir
SIR UR SO GREAT I LIKE U R TEACHING THAN OUR SCHOOL TEACHERS 🙏🙏🙏🙏🙏 WE LOVE U SO MUCH THANKU SIR
Most welcome
Answer
1nitric acid and ammonium hydroxide is used to form salt ammonium nitrate and the chemical reaction is NH4N03+H2O.
2.a.Acetic acid
b.Lactic acid
c. Oxalic acid
d.malic acid
3.Toothpaste which is a base helps prevent tooth decay by neutralizing the excess acid realised by the bacteria present in our mouth.
Nutrilisation reaction
1) Base is NH3,
Acid is HNO3
Chemical reaction:-
NH3 + HNO3 ➡️ NH4NO3.
2) (a) vinegar - acetic acid
(b) milk- lactic acid
(c) tomatoes - oxalic acid
(d) apple - malic acid.
3) Fluoride is a compound that is added to toothpaste to reduce decay. Fluoride becomes incorporate into our teeth as they develop and makes them more resistant to decay.

1.NH4OH+HNO3~NH4NO3+H2O
2.(a) acetic acid (b) lactic acid (c) oxlic acid (d) malic acid
3.when we eat food, food and sugar produces acid. The acid will form in mouth to neutral the mouth from acid we use tooth paste as mild base.
No you are wrong 😂😂
Wrong
no you are totally wrong
3:) *Tooth decay is caused by the bacteria present in our mouth already, but they inject acids into our teeth spaces when the food we eat gets stuck. So, if a bacterium release acid, toothpaste prevents it because it itself is a base.*
Because Acid + Base = Neutrality, *We can say that toothpaste prevents tooth decay.* By the way, well explained Manocha Academy.
Very good!! Correct :)

My all doubts regarding this topic is clear now. Ty sir.
1.HCL and NH4OH
2.Vinegar-Acetic acid CH3COOH
Milk-Lactic acid C3H6O3
Tomatoes-Oxalic acid
Apples-Malic acid
3.It helps to prevent decay of teeth from excess acid in our tooth by neutralizing it.
Since the reaction is between an acid and a base, it should produce salt and water right?
Shouldn't the acid be HNO3 and base NH4OH to produce NH4NO3 and H20
NaOH + HNO3. = NH3NO3 +H2O
2 a) acetic acid
b) lactic acid
c) oxalic acid
d)malic acid
3. The food we eat is a acidic one .... It may cause tooth decay. Toothpaste is a base which neutralize
@Mridul Semwal what b part ....???🤔🤔🤨🤨
@Mridul Semwal are u mad
Thank you very much
It was very helpful to me. You are teaching I a excellent way that our school teacher are not able to explain like this 👌👌👌👌👌👌👌👌👌👌😃😃😃😃👍👍👍👍👍👍👍👍🙏🙏🙏🙏👍👍👌👌👌
Glad it was helpful!
Q.3 Before we brush our teeth the pH of saliva is less than 7 that is acidic. The toothpaste contains the alkali substance which neutralizes the acid and prevent from tooth decay.
If you got your answer hit a like!!!👍👍👍👍👍
Right! Bacteria that act on food particles in our teeth also release acid which the toothpaste neutralizes.
Till date I brushed blindly. Tnq
1)NH4NO3____NH4OH+HNO3
2)vinegar -acetic acid
Milk. -lactic acid
Tomato - oxalic acid
Apple -malic acid
3)Tooth paste contain salt it neutrize acid and base so it help to prevent dacay ofteeth
Hlo sir i'm from Nepal and during the online class my science teacher usually show your videos and it is very helpful to all of us and tomorrow is the turn for this chapter soo i'm looking it before our teacher show us...thanks for the great video sir..please pin my comment so that my teacher will see while showing us tomorrow🙏🙏❤️
Glad to hear that my videos are helping you.
Sir it is very useful for me to understand Acid, Base and Salt I scored 20 out of 19 thanks sir
2 : a. acetic acid
b. Lactic acid
c.oxalic acid
d. Malic acid
3 : because in toothpaste calcium and phosphate are there to create a strong defense to prevent from cavities

Thanks 😊 sir 😄😊
Super sir best website Manocha academy for cbse students .. sir
Keep watching
Sure sir
1.NH3+NO3=NH4NO3
2.a)venigar=acetic acid
B)Milk=lactic acid
C)tomatoes =oxalic acid
D)apples=malic acid
3) this is because when we not brush it releases acid and while we are doing brush
Toothpaste is base both acid and base becomes neutralize
Sir you are the teacher I am looking for ...Thanks for helping me in clearing my concepts ... Your videos are very helpful...Thank you sir🙏🙏🙏👍👍👍👍
It's my pleasure
Sir u teach very well you should be a VIP teacher in online classes.
Thanks
A:1
HNO3 + NH4OH --> NH4NO3
A:2
a) Acetic Acid b) Oxalic Acid
c) Lactic Acid d) Citric Acid
A:3 Toothpaste contains base which neutralises the effect of acid present in decay of teeth.
A-2 (b,c,d)is wrong.
B-Lactic acid
C-Oxalic "
D-Malic "
Yes
Actually,we eat the food which contains acids and if the acidic nature is more in our teeth it may cause tooth decay so we use the basic paste to neutrilize it
Today is the only day I'm watching you and I saw your previous videos and I'm still wondering why you only have 100k subscriptions you really deserve more than that uncle much love from somalia🖤
Great to hear that you like the videos!! Thanks :) Do share it with your friends and family!
@@ManochaAcademy always sir
@@ManochaAcademy we will be sharing it bkz if only we get the knowledge it's not enough no sir
Everyone should be educated no sir
Thank you sir for your tremendous teaching

Thank you so much sir
Thank you
Thank you so much! You really have helped me tonight with my son’s lesson on Acids and Bases. We are homeschoolers and have just subscribed!
Q1
Acid + Base = Salt + water
Let's take given products to determine reactant which are acid and base so by double displacement
We get eq
NH*4NO*3+ H2O= NH*4OH + HNO *3
Acid is nitric acid and base is ammonium hydroxide
Q2. a. Acetic acid
b. Lactic acid
c. Oxalic acid
d. Malic acid
Q3. Fluorine is the halogen forming salts used tooth paste so when it combines to phosphorus and calcium present in teeth forms fluorapatite which is crystalline mineral like salt. That fluorine compound prevent us to tooth decay 🇵🇰
When pH value of mouth is below 5.5 bacteria present in mouth produce acid by degration of sugar and food particles remain in the mouth. The best way to prevent this to clean the mouth after eating food. Using toothpaste, which are generally basic neutralize the access acid and prevent tooth decay
Sir,Tomorrow I have exam for the chapter ACIDS BASES AND SALTS and this video was very helpful.
May u live for 100+ years and enrich students like us
Me2 gaving kalai neenga enga school

My name also Kalai
Oo
Q1)HNO3=acid
NH3=base
So,HNO3+NH3-----NH4NO3
Q2)a)vinegar-acetic acid
b)milk-lactic acid
c)Tomato-oxalic acid
d)apples-malic acid
Q3)Because toothpaste contains fluoride,fluoride fights against the bacteria present in our teeth and helps to prevent the decay in teeth
Thnx you dear teacher after two years so good teacher
Helped by chemistry oh my God 😭😭
Happy to help
True
Thank you
Ya
Sir that was really great even my all the doubts were cleared🙂 your explanation is very good and even you are a great chemistry teacher 👍so can you please make more videos for this lesson please sir🙏🙏
It's my pleasure
Sir,your teaching is very good.
KEEP IT UP!
Q3:when we don't wash our mouth after eating food particles settle down in our teeth.Some bacteria grow in that and produces acids. Toothpaste is a base which neutralises the acid and we can prevent tooth decay
🤚
Super explanation sir
I got 20 marks in my assessment
Thank you sir 🙏🙏🙏👏👏
Great !
Sir I had a doubt in electronic spectrum plss do aa video
Sir from where r u
Means frm which state
Plsssss reply sir
The Best explanation. I am in high schol. And this chapter is hard. But you made it easy a ton. Thx soo much . Excorage you to make such videos and I (Subscribed)
Most Welcome
@@ManochaAcademy Good Evening Sir
How does tooth paste help in tooth decaying answer:
- the nature of the toothpaste is alkaline, which is basic . They neutralize the acid produced by bacteria in mouth.
U are the best teacher sir 💜💜💜💜
Thanks for inspiring many different children about science, great job
It's my pleasure
