Properties of Zinc Carbonate
- It is a white powder, insoluble in water.
- It can be a basic carbonate which includes zinc hydroxide in the formulation
Action of Heat
On heating at 300°C, Zinc carbonate decomposes into Zinc oxide and carbon dioxide
ZnCO3 ⎯300°C→ ZnO + CO2
- Zinc carbonate is insoluble in water, but readily dissolves in many acids to form zinc salts.
