this is what I have;
add sulfate to barium = white precipitate
flouride to calcium= white
hydroxide to copper =blue
chloride to lead = white
hydroxide to iron2=green/white precipate that quickly oxidises to form brown precipitate.
hydroxide to iron3 = brown

test for anions;
carbonate add silver nitrate =white precipitate of AgCO3
SO4 add lead nitrate =white precipitate
PO4 add silver nitrate =yellow precipitate
Cl add lead nitrate =white precipitate
