Hydrogen peroxide is produced by acidifying barium peroxide and eliminating surplus water by evaporation under low pressure. Water is used to extract it, then distillation under lower pressure concentrates it to around 30% (by mass). Careful distillation under low pressure can increase the concentration to 85%. To achieve pure H2O2, the residual water can be frozen out.

Uses of H2O2:
(i) As an antiseptic it is sold in the market as perhydrol.
(ii) It is used to manufacture chemicals like sodium perborate and per - carbonate. It is employed in the industries as a bleachin

D2O can be prepared by prolonged electrolysis of water. Due to high molecular mass D2O differs from water.
NaOH+D2O → NaOD+HOD
HCl+D2O → DCl+ HOD
NH4Cl+D2O → NH3DCl+HOD
Physical Properties of H2O and D2O
Property | H2O | D2O |
Molecular mass (g mol-1) | 18.015 | 20.0276 |
Melting point/K | 273.0 | 276.8 |
Boiling point/K | 373.0 | 374.4 |
Enthalpy of formation/kJ mol-1 | -285.9 | -294.6 |
Enthalpy of Vaporisation (373 K)/kJ mol-1 | 40.66 | 41.61 |
Enthalpy of fusion/kJ mol-1 | 6.01 | — |
Temp of max. density/K | 276.98 | 284.2 |
Density (298 K)/g cm-3 | 1.0000 | 1.1059 |

Atomic hydrogen is highly reactive, whereas molecular hydrogen is rather inert. Bond dissociation enthalpy determines the chemical behaviour of dihydrogen (and, for that matter, any molecule) to a great extent. For a single bond between two atoms of any element, the H-H bond dissociation enthalpy is the highest. As a result, molecular hydrogen reacts only with a few elements.
