PREPARATION OF LEAD (II) SULFATE CRYSTALS

Diagram showing Filtration of Mixture to Remove Precipitate

SOLUBLE SALT 1 = Lead (II) Nitrate        SOLUBLE SALT 2 = Potassium Sulfate

METHOD: Lead (II) Nitrate and Potassium Sulfate is dissolved in a beaker of Water and mixed together using a stirring rod Mixture is filtered to remove precipitate from mixture Filtrate is washed with Water to remove traces of Potassium Nitrate Solution Leave in an oven to dry

EQUATION OF REACTION: Lead (II) Nitrate   +   Potassium Sulfate  →   Lead (II) Sulfate  +   Potassium Nitrate              Pb(NO3)2  (s)                    K2SO4 (s)                          PbSO4 (s)                  KNO3 (s)
