The thermodynamic characteristics of hydrogen peroxide in H2SO4-H2O solutions

The paper presents experimental data and an analysis of literature data on hydrogen peroxide forms in concentrated solutions of sulfuric acid, H2O2(aq), H3O2+ (aq), and HSO5− (aq).

The activity coefficients of H2O2 and Henry constants for solutions of H2O2 in sulfuric acid were calculated.
