Moist hydrogen peroxide can not be dried over conc. H_2 SO_4 because

Moist hydrogen peroxide can not be dried over conc. H2SO4\mathrm{H}_2 \mathrm{SO}_4 because

Options

  1. Ait can catch fire
  2. Bit is reduced by H2SO4\mathrm{H}_2 \mathrm{SO}_4
  3. Cit is oxidised by H2SO4\mathrm{H}_2 \mathrm{SO}_4
  4. Dit is decomposed by H2SO4\mathrm{H}_2 \mathrm{SO}_4

Correct answer

D. it is decomposed by H2SO4\mathrm{H}_2 \mathrm{SO}_4

Step-by-step solution

Conc. H2SO4\mathrm{H}_2 \mathrm{SO}_4 decomposes H2O2\mathrm{H}_2 \mathrm{O}_2, thus H2O2\mathrm{H}_2 \mathrm{O}_2 can not be dried over it. H2O2+[O]⟶H2O+O2\mathrm{H}_2 \mathrm{O}_2+[\mathrm{O}] \longrightarrow \mathrm{H}_2 \mathrm{O}+\mathrm{O}_2
