Mam,why have to use 85*X formula to prepare standard solution of HCl according to Indian pharmacopoeia? X is the percentage strength 🙏🙏🙏 And 54*X in case if h2so4?🙏🙏🙏🙏🙏🙏
Hello mam I have N/10 solution of EDTA what quantity I have to add in 1000 ml distilled water.the titration is carried for water testing . please reply Ma'am .
+ashish kumar It depends on how much molar or normal solution you want to prepare..Usually we prepare a stock solution with higher Normality or Molarity so that using dilution method we can prepare the required concentration of solution. Hope this helps.
thank you so much.......i dont how to express my happiness....true teacher.
Very nicely explained thank you soo much 🥰 ma'am
Really awesome I needed about this topic mam and gratefully thanks

X is the percentage strength 🙏🙏🙏
And 54*X in case if h2so4?🙏🙏🙏🙏🙏🙏
Thanks verymuch
mam How 1M= 2N i think its typo because Normality= Molarity*n factor
Thank you mam your video help me a lot🙏🙏
Glad to hear that
Nice explain
M=1/2N
Then N=2M
To Aap 1M=2N kaise likh dia
Exactly, same doubt for me too
Very much informative..Tku so much maam

Thanks. Glad it was helpful.
Can you explain about difference between molarity and normality
Hi, how I can calculate density of 80% sulfuric acid? Please guide me❤
Thanks so much
Iam prepared more times 0.1N KOH but after standardization it is not reaching preparing normality what is the reason
Mam why you put 49
Madam please explain purity base 1N KOH preparation and calculation
❤ thank you mam
How did you get 5.44 ml for 0.1 M solution? Thank you
the equivalent weight is directly calculated by( m/valency ) and then the relation is identified m=2n

98gm or ml for 1n?
Thank you so much ma'am
there is some conflict to convert Molarity to Normality, kindly resolve it!
N= 2M Or M= 2N ??????????????
