Question

Which of the following reactions is Merck's method to prepare hydrogen peroxide?

विकल्प

• \[\ce{BaO2.8H2O_{(s)} + H2SO4_{(dil)} -> BaSO4_{(s)} + H2O2_{(aq)} + 8H2O_{(aq)}}\]

• \[\ce{Na2O2_{(s)} + H2SO4_{(dil)} -> Na2SO4_{(s)} + H2O2_{(aq)}}\]

• \[\ce{BaO2_{(s)} + H2O_{(l)} + CO2_{(g)} -> BaCO3_{(s)} + H2O2_{(aq)}}\]

• \[\ce{3BaO2_{(s)} + 2H3PO4_{(dil)} -> Ba3(PO4)2_{(s)} + 3H2O2_{(aq)}}\]

Answer 1

\[\ce{Na2O2_{(s)} + H2SO4_{(dil)} -> Na2SO4_{(s)} + H2O2_{(aq)}}\]

Explanation:

When sodium peroxide reacts with dilute sulphuric acid, sodium sulphate and hydrogen peroxide are produced. Merck's Method is what it's called.

\[\ce{Na2O2_{(s)} + H2SO4_{(dil)} -> Na2SO4_{(s)} + H2O2_{(aq)}}\]
