Thank u sir so much......for ur beautiful explanation.....I now understand the reaction and now I find chemistry a but interesting after seeing ur videos thank u ❤❤....
Thank you so much for this video!! I have been having a hard time understanding this chemical change and found it boring but through your video i learned it in a way that i will never forget and you made it very interesting. You did a great job making me scientific!
Sir could u please tell that where is iron in the solution which makes feso4 .... The iron nail u took out which had copper deposition so only sulphate solution is left right ... How iron is included in it
after the displacement reaction when copper sulphate in solution gets displaced by iron present in the nail ,the copper particles displaced will settle around the nail and on the bottom of the flask in brown colour
Cu2S can be prepared by heating copper strongly in sulfur vapour or H2S. The reaction of copper powder in molten sulfur rapidly produces Cu2S, whereas pellets of copper require much higher temperature. Cu2S reacts with oxygen to form SO2: 2 Cu2S + 3 O2 → 2 Cu2O + 2 SO.
Sir, I need your help. I am making nickel sulphate while I am not maintaining its pH. When nickel and sulfuric acid are reacting, the head turns into crystals. After the crystal dissolves in water, the PH reaches 1.3 when the PH should be 6.0. Can you tell me how to change PH from 1.3 to PH 6.0?
Helps in understanding a lot and now I find my ncert book interesting
Same with me 😁😁😁😁😁
Ikr same
Yaa u are right 👍🏻
Which class?
Which class
Finally I understand this reaction with help of u .. thanks sir
Thx a lot sir for this...this kind of teaching methods must be implemented in the schools for making learning process better way thx again sir...😊
Thank you for watching the video
@@MakeMeScientific 😊✌️
@@MakeMeScientific sir I need your please
This video helped me a lot for preparing for my model exam
Thank u for the video I can understand what was in the book after seeing ur video I understand
Thank you for watching the video 🙏
Yes sir
Thank u so much sir ....u really helped me understand it...ur way of explanation is great
Thank u sir so much......for ur beautiful explanation.....I now understand the reaction and now I find chemistry a but interesting after seeing ur videos thank u ❤❤....
Thanks for watching the video 🙏🏻
I really appriciate you sir
Thank you so much....
It was very easy to understand by your video.....
You demostrated it very well... 😊
Thanx a ton sir. Your video helped me a lot in my exams... Looking for such great videos in future
Thank you
Thanks for making us understand , now interested in activities.
Thanks a lot sir 🙏🏻🙏🏻
fantastic, sir
Thanks sir it's help me a lot to understand the rxns. 👍🙏
Nice explanation sir . Thanks a lot 😊
Very amazing sir.👍👍
Thanks for explaining sir,
And i was strangely disgusted when i saw the nail in the ferrous sulphate............😶
It help me to understand.
helped*
Our teacher showed us this in lab
GOOD VIDEO, VERY USEFUL FOR THE STUDENTS
Nice 🙂
Excellent demonstration💯
It helps me to make my project
Thanku it helped me a lot👌
ㅤ
Amazing tq so much
Welcome 😊
🙏 for explaining
Thanks sir helped a lot😊
Could have added sulphuric acid (dilute) to speed up the reaction
Thanks for suggestion
i also understand this topic because of you sir . thank you
HELPED ME A LOT 😊
Nice explanation sir, thanks a lot.

Thanks for watching the video 🙏
Thank you very much 😊
That's help me very much
You're welcome 😊
Nice
Tq, it was interesting
This reallyyyy made me 👩🔬 *scientist
Thankyou so muchhhh
Thanks sir
helped a lot sir..thenk you
Best..
Thanks Sir U Are Great.....☺️☺️☺️☺️
Please check updated version. Thanks
well sir as you said the reaction is slow wouldn't a catalyst do the slow process fast
Yes . Reactions depends upon the concentration of reactants also
Thanks
To fast this reaction you can add catalyst
good to know
to speed up*
Thank you for making this video
That's cool video.
Can we add a catalyst to increase the speed of the reaction?
I havent tried. But no need of catalyst as reaction results are seen within 15 minuted
Nice sir
Sir... You had done some mistake the layer of sulphate is stick on the surface of iron nail... But keep working doing well
Thanks for watching. Please see the updated version of the video check out the link in the description
@@MakeMeScientific ... Ok sir..
I am also a youtuber it is very understanding standing
सर जी आप बहुत अच्छे प्रैक्टिकल डेमोंस्ट्रेट करते हो पर हिंदी में भी डेमोंस्ट्रेट कर दिया करो इंडिया हिंदी समझता है
OK sure
Thankyou Sir 🏵️
Our teacher showed us this
Sir ye experiment mein toh colur pura wight tha,slightly green nhi tha ,book mein dekha toh pura green hi jata hai
Please see the updated version of the video check out the link in the description
@@MakeMeScientific sir there is no link in description
Thanks 😊😊 sir
👏👏🤙🤙
tHANK U FOR THE VIDEO
I have a question in ch 2 learnt that we generally don't add water in acid we usually add acid in water bec it is highly exothermic why?
Yes you are correct. thanks
Is it distilled water that u mixed with copper sulphate salt?
Yes
Sir could u please tell that where is iron in the solution which makes feso4 .... The iron nail u took out which had copper deposition so only sulphate solution is left right ... How iron is included in it
FeSO4 itself contains Iron.
Don't we need to add dil sulphuric acid to the copper sulphate solution?
Not required
sir but why isn't the ferrous sulphate in green color?
The green is very very pale
Thankyou 🙏🙏🙏
Add more couper shalphet then it contains green color
Green colour is due to the formation of iron sulphate
👍🏻👍🏻
what to do for rippling the iron needle from copper 🤔
You can simply remove it with spatula
Did your teacher show you this
You can speed up the reaction by gently heating
Thanks for providing information
@@MakeMeScientific sir please I need your num
But that's a screw. I only have nails. Will it still work?
Yes
If yes then how can it be because in my book it says that iron rusts in the presence of water and oxygen only please help me to understand that doubt
This is not rusting only brown color is due to the formation of copper on Iron
Mmmm😊
👍🏻👍🏻👍🏻👍🏻
magic
Nice but some resound
Thanks for suggestion
i dont think you should touc the copper because it might be poisonous?
When taken inside huma body its poisonous otherwise ok
Sir which exam should I write to become a chemical engineer?
Jee
@@MakeMeScientific ok sir thanks
ㅤ
Bhai kaise kiya bata de na🔥🔥
Which change is this? It is chemical or physical ??
Chemical
Iron nail se iron nikale ke baad copper usme juda?
Yas yahan per basically displacement reaction ho raha hai
How to remove or seperate iron/alluminium from copper?
It's shown in updated version. Please see the link in the description
@@MakeMeScientific coudnt find the link...can you please share..here
Can we prevent this
What can be prevented? Please reframe your question
@@MakeMeScientific i mean Is it possible to change the iron nail to the old stage?
No once thischemical reaction happens it can't be reversed
Sir does it the colour of the iron sulphate fade away or dies it turn green??
Does*
Color of copper sulphate fades away and green color is of iron sulphate
Sir was that rust on the nail?
That is copper
Sir copper sulphate ko hi copper solutions khte hai kya?
Copper sulphate added in water is known as solution
@@MakeMeScientific ok thanks sir
Copper solutions issi ko bolenge na sir?
on mass scale can we use a iron bar instead if nail???
Yes
Sir are you sure the color of CuSo4 is brown???
It's blue and white when anhydrous
after the displacement reaction when copper sulphate in solution gets displaced by iron present in the nail ,the copper particles displaced will settle around the nail and on the bottom of the flask in brown colour
I guess it is Fe+cuso4=Feso4+cu
Not cu+Feso4 (in products)
We can wait for half an hour (my sir said )
2:17 did you clean it with sand paper????
Please see the updated version of the video. I did clean it
Sir Do you make video of explaination of sci for Class 7?
Yes
Can we use h2o2 as catalyst here
What's that slightly green color liquid?
Iron (ii) sulphate
Sir is this a precipitate reaction?
Displacement reaction.
