Substances used for its preparation |
Equation |
| 1. By precipitation |
PbCl2 |
Pb(OH)2' HCI (Lead hydroxide and hydrochloric acid). |
Pb(OH)2+2 HCI → PbCl2 + 2 H2O |
| 2. By action of acid on metal |
ZnSO4 |
Zn, H2SO4 (Zinc granules and sulphuric acid). |
Zn + H2SO4→ ZnSO4+H2 |
| 3. By action of acid on oxide |
CuSO4 |
CuO, H2SO4 (Copper oxide and sulphuric acid) |
CuO + H2SO4 →CuSO4 + H2O |
