Why does that looks like she has been held in a gun point😅.. Anyways... Thnx a loooooooooootttttt mam... You have no idea what these videos mean to us.. loads of thnx
my teachers would've surely noticed my nails if they were that long . and they literally stop teaching us , just to scold us nd waste time . wow . it's the only reason i have to watch a practical video on youtube onscreen (where i could've done these practically) !
Lol😂... Leaving your practicals just cause you don't want to cut down your nails... That's ridiculous... Cut down your nails and perform these practicals, otherwise the examiner will cut down your marks😂
Ma'am for group 3 can we add the salt solution to dil Hcl and then add nh4cl and nh4oh 🤔.. I always get confused whether we need to add dil Hcl or not? 🤔
wil we be provided with ferric salts only? or would we have to oxidise too? and why was the solution heated after adding nitric acid? do we have to heat before adding nh4cl even when we have the ferric salt? thankyou for the video.

I tried this test so many times today. But didn't get the result. But now I know, I might have prepared the solution in HCl that's why I didn't get the ppt

Ma'am for group 3 can we add the salt solution to dil Hcl and then add nh4cl and nh4oh 🤔.. I always get confused whether we need to add dil Hcl or not? 🤔
You should restart with the fresh salt solution for group 3 then add NH4Cl followed by NH4OH

Thank you 😊 ma'am ,ye os kya hota hai please bataiyega please
OS is the short form of original solution .
So just take a pinch of given salt and add around 2-3 ml water to dissolve it. That's your OS.
Mam i have a ques Fe+2 comes under the group 2 or group 3?
Group 3
