In this video, we look at how to test for the presence of the sulfate ion. First we look at the sulfate test. We then explore the advantage of using barium nitrate rather than barium chloride. Finally, we look at how to deal with the presence of carbonate ions, which can give a false positive.

Would you make a video on organic chemistry 2 and 3. Those two topics would take a long time to fully understand plus they are worth a lot of marks

thank you!!!!

Sir please do a video under foetal circulation 🥺
@adambennett234 Says:
when will you finish making all ur alevel biology and chemistry videos?
@samnewmarch06 Says:
When do you aim to finish all A level biology and alevel chemistry videos?
@gcsestudent2778 Says:
hello sir, thanks for the video. helpful as always.
I just wanted to ask that have you finished making all the a-level biology and a-level chemistry videos for year 12? as I started my A-levels in 2022 sept
Also, there is no video on eqiulibria constant in the equilibria and kinetics playlist......

Amazing video sir! Love your style of teaching :)
@ahmedibrahim9082 Says:
Can you please make separate playlists for AS and A levels ?
@kazz364 Says:
Hi Sir Do you know approximately when you will have done every video for A level chemistry and if you will be making workbooks for it and biology as it was extremely helpful during gcses
