Thank you sirr for question
Sir thank you sir appke videos achhe h sirr💯
Thank you sir
Thank you
😊
👍welcome
Thank you sir
Sir voice clear nhi hai but explain accha kiya hai Thankyou sir❤
welcome 👍
😊😊
River water or dam water me TSS ka kitna difference rehta hai????
Nice Please Upload More Viva Questions on Chemistry Lab Experiments.
Ph range of methyl orange is given wrong it is 4.5 to 8.3ph plz don't miss guide students
The pH range of methyl orange ,according to you is 4.5 to 8.3 is totally wrong. The correct pH range is 3.1 to 4.4 piz don't confuse the students
Jyada bod rha to dilution Krna pdta hai wo kayse krenge aur kayse formula me lagayenge aur flask ko marking tak nhi bhara tha uske upar bhara tha to 125 ml kayse hua
1 gm dicromate ka equivalent weight kitna hoga sir
Thank you sir :)
Welcome 👍
Really very helpful thanku sir
Welcome 👍
Watching before the day of of exam😂😂
Thank you sir
Welcome 👍
Thank you sir.
Welcome 👍
Very clear explanation thanks a lot sir
Welcome 👍
Sir Equivalent weight 22 kaise aaya hai .. Plz explain kar dijiye .. With lot of respect and love ❤❤
Carbon dioxide molecule is reacting with two Hydroxyl ion, so the equivalent weight of CO2 is 44/2. = 22
@@chemilabs5101 Thank You so much Sir ☺️☺️
Thanks Sir 🙏🙏🙏
Most welcome
THANK YOU SIR
Welcome 👍
Very helpful video
Welcome 👍
Sir, swirl pattern in phenolic resin resole
Welcome 👍

Welcome 👍
whats the E in NxE sir?
E is equivalent weight of CO2
Mike use kro
Sir jab dobara reading ke liye experiment krenge to burette dobara se 0 tk fill krni pdegi?
Koye jaruri nahi hai
Thanks sir 🙏
Welcome 👍
Sir Good Night 🌉
Good night 👍
Thanks sir
Can you give other experiment viva question ?
Thank you sir
Welcome
How to download this pdf sir
Take the screen shot of viva-voce
@@chemilabs5101 ok ,sir
Sir what is the normality of dilute sulphuric acid used in sample preparation?
Normality of dilute Sulphuric acid should be 5N.
@@chemilabs5101 thank you sir .one more query: same 5 N sulphuric acid has to be added while sample preparation and also during titration (10 ml)?
Yes
@@chemilabs5101 thank you sir...add more videos of practicals please, we learn a lot from it
What we do with the final result as powder ? Because i tried to disolve it with water to make glue but it s not working
Your question is not clear.
Sir please attach pdf🙏 Some words are not clearly visible in video
Please set the quality of mobile at 720 to see the clear words
@@chemilabs5101 Yes sir it is already at 720p.
Last me calculation ke time carbonate and bicarbonate ka formula kaise la rahe hai?
Thank you sir 😊
Most welcome
🙏
Welcome 👍
you saved my day
Easy!
Welcome 👍
The name of catalyst used formation of urea formedehyde
We used acidic catalyst conc. H2SO4 for the formation of urea formaldehyde resin.
@@chemilabs5101 thanks sir
Awesome 👍🏻
Welcome 👍
Sir waiting for your reply
To prepare N/30 K2Cr2O7 solution, take 1.6 grm K2Cr2O7 dissolved in one litre of distilled water. To prepare Potassium ferricyanide indicator, take 2 grm of salt dissolved in 250 ml of distilled water. To prepare water sample one grm of Ferrous ammonium sulphate dissolved in 50 ml of dil H2SO4 solution and filled upto one litre of distilled water.
Super sir
Welcome 👍
Good morning sir Please tell me sample preparation Indicator preparation Known solution preparation
Welcome 👍
Thank sir🙏🙏🙏🙏🙏
Most welcome
