Question
Give a method for the manufacture of hydrogen peroxide and explain the reactions involved therein.
Solution
Industrial preparation: \[\ce{H2O2}\] is prepared by the auto-oxidation of 2- alkylanthraquinols
2-ethylanthraquinol ↔ \[\ce{H2O2+}\] oxidised product
\[\ce{2Fe^{2+} (aq) + 2H+ (aq) + H2O2 -> Fe3 (aq) + 2H2O (l)}\]
\[\ce{PbS (s) + 4H2O2 (l) -> PbSO4 (s) + 4H2O (l)}\]
