Hi I have my AS qualitative (ocr) coursework in a few days time on identifying four unknown solutions and investigating reactions between solutions etc etc and I need help with two questions that I have come across that are related to this topic.
1) What would the student observe when testing H2SO4, KI, KBr and HCl with universal indicator?
2) What would the student observe when testing H2SO4, KI, KBr and HCl with K2CO3?
I was especially confused with number 2 because I am not sure how KI and KBr can react with K2CO3
Thank you very much
ALSO if the question asks you what is this colour for this test tube or something and there if a solution at the bottom which is say green for example and a small sort of solution on top of that which is yellow, which colour do you give?
