Thank you sir for all that you do to help students around the world excel.Thank you for taking the time to do each video.God bless you and your family.
long route, is you do m1v1=m2v2 , where m1= 0.5 M, v1 =20 ml, and v2 = 30 ml, M2=unknown you don't need conversion at all. 0.5*20=30*M2, solving for M2=10/30, or 0.3333. That is the M of the other solution and if you need moles, you can figure it out with ever needing to convert NaOH into mols...the only problem with m1v1=m2v2 is if there are multiple Hydroxide (OH) or Hydronium (H+) ions
Thank you sir for the video, it is very helpful for me :) Permission to ask sir.. 1. Can you please explain, sir, why the burette must be rinsed first with the titrant solution? 2. Then why NaOH if stored for a long time will look watery? 3. I also want to ask, sir, for example, we do a titration between a weak acid (oxalic acid) as a sample, and the titrant is a strong acid (NaOH), and use the PP indicator. So, is it possible if we reverse the position of the sample and the titrant, so that NaOH is the sample and oxalic acid is the titrant, is it possible, sir? And whether the indicator can be used with the same type ..? 4. And for example, sir, it is known that the concentration of the mother liquor is 0.1 M, then we will make 100 mL of a solution with a concentration of 0.05 M from the mother liquor. How do we do it, sir? Thank you sir..🙏🏻
SORRY IAM A YEAR LATE BUT we rinse the burrete with the titrant to make sure that solution does not dilute(even if in smallest amt) due to the presence of water in the burette
Question : initially we add phenolphthalein and Get Pink Colour so How we get to know that this is the color of Neutralization? Because Phenolphthalein Always Gives Pink for Acid
Please sir make a vedio this topic" A study on the application and adverse effect of pesticides and a human life and environment " 200 Words please sir
I think one fine day your channel create history in all of chemistry TH-cam channels
Thank you so much for your love and support.
🙏🙏🙏❤
Ur right!
Yes❤❤
Right🎉🎉
Right
Good communication+ visual understanding= 🔥📈
you could not explained better than this, God bless you.
You teach confusing concepts with so much simplicity, Thank you so much!!!!!!!!!!!!!!!!
I really cant thank you enough for this amazing video
I'm a third year Chemistry student.Never understood that before😂. ...... Thank u so much for explaining ❤❤🎉🎉
planning to take chem in clg, where are you studying?
UR VIDEOS HAVE BEEN HELPING ME SINCE 10th THANK YOU SO MUCH SIR ☺️
Wow!! Superb sir 👌👌We want more chemistry practical videos
the first video to actually mak me undertand respect😭🤝
I have ever saw the such elaborated and knowledgeable video on TH-cam 👏
I have no word to express your teaching method
Ur accent is one of the reasons I understand ur lesson keep it up
Love you sir for such a beautiful explanation with examples❤
I didn't waste my time it's understandable and comprehensive 😁I will like that you should also explain for redox titration
Thank you sir for all that you do to help students around the world excel.Thank you for taking the time to do each video.God bless you and your family.
Thank you so much Najam academy, you have been so helpful for my upcoming JUPEP exams in University of Ilorin, Nigeria. Much Love ❤❤ from Nigeria 🙏
first time coming against this channel found it really helpful keep up the good work bro
Really... you make things simpler and easy to understand.. Thank You So Much Sir... Lots of love from Nepal
your explainations are soo good
Oh my goodness , thank god I found this channel , the explanation was just sooooooooo amazing , earlier it was the toughest topic for me

What to do in case of multiple Hydroxide such as KOH and NaOH
You are a life saver in chemistry sir thanku so much for being there ☺️
Thank you sir for the video, it is very helpful for me :)

For
1)strong acid/strong base
Burette sol- strong base
Conical flask - strong acid
Indicator - phenolphthalein
2) strong acid/weak base
Burette sol- strong acid
Conical flask - strong base
Indicator - methyl orange
3) weak acid/ strong base
Burette sol- strong base
Conical flask - weak acid
Indicator - phenolphthalein
I realy like your video it makes chemistry very easy
I have no words, amazing sir
You are best chemistry teacher than my tution teacher 😊😊
Thanq soo much. 3 period lesson in 10 minutes
Sir pls do more videos in organic chemistry 🙏
Sir please make video on sterio isomerism
I will...
🙌🙌🙌🙌
@@NAJAMACADEMY😮
One of the best channels for students , thankyou 😊
u are a life saver thank you!
Best explanation with the best method.....
Make videos on every chemistry topic please, the world wants you
I think I have gotten solution to my problem
Thanks ❤❤
Best channel to study chemistry ⚗️🧪👍🙏
Very interesting sir 👍
the best expalination from scratch to toppers batch xD!
Thanks dude. This helped a lot.❤
i never understood this before now! thank you so much!!
what does 20cm cube means thats what many ppl lack like they don't t know the actual meaning of the answer & you made it so understandable thank you
Wow you are a genius . Very nicely explained❤❤❤

Please can you do REDOX titration. Thank you.
Sir great ❤️ and 🙏🙏🙏
bro call me racist, but I can't concentrate on the lecture for a minute straight without a giggle , the accent is so funny😭
That's true buddy
😂
Becoz!u concentrate on the accent compared to the helpful teaching !
Well, when u have a schizophrenia bipolar tendency. Najam academy is d best to me when it comes to chemistry tutorial on TH-cam. Love❤❤❤ from Nigeria
RACIST!!!!!!!
Please next video is photochemistry pe banavo sir 🙏🇨🇮👍🎉🎉👍👍
Thank you sr
I can't understand that how the concentration of HCl is greater than NaOH when the volume of HCl in titration is also greater than that of NaOH
