Lead (Pb) and water - Water Treatment and Purification
Lead (Pb) and water - Water Treatment and Purification

A small ,lead, oxide (PbO) layer forms at the surface of the metal. When both oxygen and water are present, metallic ,lead, is converted to ,lead, hydroxide (Pb(OH) 2): 2Pb(s)+ O 2 (g) + 2H 2 O(l) -> 2 Pb(OH) 2 (s) Solubility of ,lead, and ,lead, compounds. Elementary ,lead, does not dissolve in water under normal conditions (20 o C, and pressure
