One way to remove lead ion from water is to add a source of iodide ion so that lead iodide will precipitate out of solution: pb2+(aq) + 2i-(aq) = pbi2(s).
a. what volume of a 1.0 m ki solution must be added to 100.0 ml of a solution that is 0.15m in pb2+ ion to precipitate all the lead ion?
b. what mass of pbi2 should precipitate?

Predict the reactants of this chemical reaction. that is, fill in the left side of the chemical equation. be sure the equation you submit is balanced. (you can edit both sides of the equation to balance it, if you need to.) note: you are writing the molecular, and not the net ionic equation. > cacl2(aq) + h20(l)
