Add a suitable amount of zinc oxide (in suspension or powder form) to an acidic solution containing an appropriate amount of water, typically using sulfuric acid as the acidic solution. Stir the solution to ensure thorough reaction. The reaction will produce zinc sulfate monohydrate. ZnO + H2SO4 + H2O → ZnSO4·H2O ZnSO4·7H2O is a compound that contains seven molecules of crystalline water.
Chemical reaction process: Add a suitable amount of zinc oxide (in suspension or powder form) to an acidic solution containing an appropriate amount of water, typically using sulfuric acid as the acidic solution. Stir the solution to ensure thorough reaction. The reaction will produce zinc sulfate heptahydrate.ZnO + H2SO4 + 7H2O → ZnSO4·7H2O
