Jabardast mashallah sir, hamari mam jo 1 saal me nahi samjha payi wo aapne bas 10 minute me samjha diya 😭💉💦. Mai aapka bahot shukraguzaar hu sir 😘❤️. Jazakallah khair.
Polyoxyethylene alkyl ethers demoted by formula C(n)E(m), are nonionic surfactants made of an alkyl chain (C) with 'n' methylene groups and a hydrophilic part with 'm' oxyethylene units.
0.5g stearic acid was taken in procedure, but according to definition we have to calculate values per gram. So, to get per gram value we have to multiply by 2... I hope you understand... If not, please WhatsApp me on 9925064346
Good day, First if all nice video however I have a small question, I can do the saponificacion number (S) by titration because the GMS-K is a salt and it is neutralized with de HCl but if I want to determine S from an ethoxylate alcohol?

Actually i did not get your question. Can you elaborate your doubt ?
@@KhalifaMAsif sure:
I would like to know how to determine the HLB value in a non ionic surfactant such as tween 80 or laureth-5
At what temperature reflux it
