ma'am aapko aise hi sare comments aate honge, but 5 hours from now i have my practical, and ma'am ek bhi salt analysis nahi aa raha tha, aapka ye video dekhke ab dimaag me rat gaya hai, let's see kya hota hai but thankyou so much for this !!!!
Maam today was my practical exam, and i do titration full charts with experiment nicely and i completed my practical exam today..... Maam titration and salt analysis appse hi sikha tha mainee, thank u maam for this help... And i answered 4 question out of 5 in viva,,, and teachers ask those questions that u tell in classes of practicals...... My name is surya and i am from Assam and thank u for your this help and for our final exam 8 days left... Keep blessing 😊😊😊😊
Ma'am another doubt plzz - In salt analysis experiment, in the part of BaCl2 test --- First we add the given salt (which is unknown) in the beaker. Then we add water after that we add BaCl2 in that beaker... If it doesn't make white precipitate, we will go for dil. H2SO4 experiment.. But, If it makes white precipitate we have to add dil. H2SO4... Now if white precipitate dissolve in dil. H2SO4 , then the given salt will be Sulphite ion... And If white precipitate doesn't dissolve in dil. H2SO4, then the given salt will be sulfate ion.. Am I right till now... Plzz reply ma'am... And my question is how I will determine that white precipitate either dissolve in dil. H2SO4 Or not... Plzz reply ma'am.. 😞😞
@@AparnaBhardwaj2020 Firstly nitration of benzene then reduction of nitrobenzene in the presence of sn+HCl gives aniline then aniline react with nitrous acid to give di azonium salt and in the presence of HBF4 it gives Flourobenzene.
Ma'am this is the only method to form flourobenzene my teacher thought me I want to give this reaction in very short steps thats why I'm starting research in laboratory because halogenation is not possible.
Ma'am tomorrow I am having my chemistry practical...and after watching ur video...I am bindass..thank you so much ✨❣️

Mam is it wrong if we add conc h2so4 in salt solution rather than just salt

Not exactly
Please watch my full video of salt analysis

@@AparnaBhardwaj2020 ok ma'am
Mam how can we form flourobenzene
Add HBF4 followed by heating to diazonium salt....u can find this reaction in amines chapter last third page of ncert

Yes
Absolutely, but we can start writing directly from diazonium salt also
Ma'am Kal term 1 practicals hai, cbse se toh nahi aayenge but mere school ke teachers bhi bhayanak hai itna dar lag rha hai😥
Padh k jao far ki kya baat hai betu.
All the best
Mam is observation table is given in exam ? Is Confirmatory test procedure also given in exam ?
Only aim will be given
