Lead (II) Iodide Percipitate
Lead Iodide percipitation. Pb(NO3)2 (aq) + 2KI (aq) → PbI2 (s) + 2KNO3 (aq) Lead Nitrate and Potassium Iodide solutions are mixed to make signal yellow Lead Iodide percipitate. The lead iodide percipitates out because of the extremely low solubility of LeadIodide, 0.063g/100ml @ 20*C.
