You can find all my A Level Chemistry videos fully indexed at www.freesciencelessons.co.uk/...
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.

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......

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
