    I'm going through CH2 past papers and I'm stuck on this question. What's more, I can't find any information that would help me to answer it in my textbook OR revision notes from class. I'd be really grateful for some help with answering it!So yeah, here it is:

    Ba(OH)2 contains barium ions. Note the reactant you would add to this solution to show the presence of barium ions, by giving the result of the test. (2 marks)

    Thank you thank you thank you !!
