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 120.0 mL of a solution that is 0.23 M in Pb2+ ion to precipitate all the lead ion?

L I−

(b) What mass of PbI2 should precipitate?

g PbI2

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
