Anyone can help me with a solubility chemistry question:
A lead (II) sulfate precipitate can be dissolved if a) We add an acid. b) We add EDTA. c) None of the above is true.
I think EDTA is a ligand, and if you want to dissolve the sulfate, then Pb sticks with EDTA to form a complex. And so more Pb will be formed to balance the reaction.
