Question

In lab H2O2 is prepared by (A) cold H2SO4 + BaO2 (B) HCl + BaO2 (C) conc. H2SO4 + Na2O2 (D) H2+O2

Tardigrade Admin · Accepted Answer

In lab H2O2 is prepared by reaction of BaO2 ⋅ 8H2O and H2SO4(cold). A paste of BaO2 ⋅ 8H2O is prepared in ice-cold water and then added gradually to ice-cold dilute sulphuric acid. underset text Barium peroxideBaO2 ⋅ 8H2O + H2SO4 → BaSO4 downarrow +H2O2 +8H2O Barium sulphate precipitates out leaving behind a dilute solution of hydrogen peroxide.
