Question

Give one method of preparation of hydrogen peroxide.

Answer 1

Hydrogen peroxide is prepared by the electrolysis of 30% ice-cold H2SO4. When acidified sulfate solution is electrolyzed at high current density, peroxodisulphate is obtained. Peroxodisulphate is then hydrolyzed to get hydrogen peroxide.

Hydrogen peroxide Chemical formula: H2O2

Boiling Point: 150.2 °C

Molecular Weight/ Molar Mass: 4.0147 g/mol

Density: 1.05 g/cm3
