A50 ml lead nitrate solution, Pb(NO3)2 is mixed with a 50 ml solution of potassium chromate, K2CrO4 , and a yellow precipitate forms with a mass of 16.160 g. Since most potassium salts and nitrates are soluble in water, PbCrO4 must be the precipitate. The equation for this reaction is: Pb2+ + CrO4 2- -> PbCrO4.
Calculate the theoretical yield using the starting quantities of both reactants.
