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 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
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
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
Can we use NaOH in flask and HCL in burette and use phenolphthalein indicator.? Is it fine to have colour change from pink to colourless????? Pls answer me😢😢😢😢😢
I think one fine day your channel create history in all of chemistry UA-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 ☺️
the first video to actually mak me undertand respect😭🤝
I have ever saw the such elaborated and knowledgeable video on UA-cam 👏
I have no word to express your teaching method
Wow!! Superb sir 👌👌We want more chemistry practical videos
Oh my goodness , thank god I found this channel , the explanation was just sooooooooo amazing , earlier it was the toughest topic for me
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 🙏
Ur accent is one of the reasons I understand ur lesson keep it up
You are best chemistry teacher than my tution teacher 😊😊
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.
You teach things in a simple way. Good job najam
I didn't waste my time it's understandable and comprehensive 😁I will like that you should also explain for redox titration
your explainations are soo good
Thanq soo much. 3 period lesson in 10 minutes
You are a life saver in chemistry sir thanku so much for being there ☺️
Love you sir for such a beautiful explanation with examples❤
first time coming against this channel found it really helpful keep up the good work bro
I have no words, amazing sir
Really... you make things simpler and easy to understand.. Thank You So Much Sir... Lots of love from Nepal
One of the best channels for students , thankyou 😊
Very nice teaching man ❤😊
u are a life saver thank you!
I realy like your video it makes chemistry very easy
Thanks sir itna badhiya se batane ke liye 😍😍😍😍
the best expalination from scratch to toppers batch xD!
Best explanation ever 💯
😭😭he teaches so good..
Very interesting sir 👍
Beautiful expln❤
Best explanation with the best method.....
Thanks dude. This helped a lot.❤
Guys admit it! you like Najam Sirs lecture because of his soothing voice.
Best channel to study chemistry ⚗️🧪👍🙏
Amazing method of teaching❤
Thanks a lot sir for this video🙏🙏
One of the best lecture sir🎉🎉
Your explanation is exciting ❤
Thank you so much, sir 😄😄
Sir please make video on sterio isomerism
I will...
🙌🙌🙌🙌
@@NAJAMACADEMY😮
Wow you are a genius . Very nicely explained❤❤❤
i never understood this before now! thank you so much!!

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
Made salt analysis easy ❤
Clear explanation...🤩
I think I have gotten solution to my problem
Thanks ❤❤

What to do in case of multiple Hydroxide such as KOH and NaOH
Thanku sir it is very help full to understand titration
Fantastic explaination🎉
Literally thanks sir ji
Most amazing vedio Keep it up sir .may Allah give you more success
Thank you sir 😊😚
This helped a lot
Make videos on every chemistry topic please, the world wants you
Sir cab you do a video of titrimetric analysis it's classification principle normality molarity molality ppm ppd etc
I understand easily through this
the best video thank you sir
A video on resonance
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
Chemistry class 12 viva attendence
Sir pls do more videos in organic chemistry 🙏
Superb sir, thnkuu.soo muchh, your way of teaching is impressive

Sir kindly urdu mn bhi lectures dn esy sequence aur examples k sath❤
Mashallah
Can we use NaOH in flask and HCL in burette and use phenolphthalein indicator.? Is it fine to have colour change from pink to colourless?????
Pls answer me😢😢😢😢😢
Nice vid man
That was so helpful:grade 12 in Kurdistan 🙃✌️
Sir Please upload more videos on stechiometry
Amazing
THANK YOU!!!!!!!!!!!!!!!!!!!!
Sir explain unit cell in chemistry
Can we take NaOH in flask?
We could also equate the gram equivalence to get the answer

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 UA-cam. Love❤❤❤ from Nigeria
RACIST!!!!!!!
Explain ellingham diagram pls 🙏
