text: Based on studies showing that hydrocerussite (Pb 3 (CO 3 ) 2 (OH) 2 ) and cerussite (PbCO 3 ) are widely observed in the corrosion scale   , batch dissolution experiments were conducted using pure hydrocerussite and cerussite solids to investigate the lead solubility under different pH values (7.0, 8.0 and 9.5) and temperature conditions (20˚C and 5˚C).
