BLUE LAKE Test for Aluminium ions in Laboratory NEET/JEE 2025 BY Seema Makhijani.

[@shlok3172]

I have observed that all chemistry teachers have one thing in common-their confident accent. Great demonstration mam👍

[@seemamakhijani721]

🙂🙂

[@abhinav6979]

That's one of the reason why they are our teachers.

[@siddhantgodara837]

There are always exceptions 😅

[@jungkookie411]

Yeah u are absolutely right

[@Divyanshu_yadav700]

Cause they have been doing the same thing for past 15-16 years

[@stellarbts4181]

I'm a bit jealous of this teacher. Ours just make us memorise everything and doesn't even help us and just scream at us when we ask questions. Other than lab times she's good.

[@bighands9078]

Same with our physics teacher 😮

[@vaibhavjaiswal471]

Suddenly her video on test for Aluminium and sulphate ion got a whopping 33K views.Thats the power of board exams since it is the salt to be asked in ISC 2020 chemistry practical. Lol😂🤣🤣😂😂 Great videos though.
