Addition of H _ 2 SO _ 4 to BaO _ 2 produces

Addition of

{H}_{2}{SO}_{4}

{BaO}_{2}

produces

Options

A $BaO, {SO}_{2}$ and ${H}_{2}O$
B ${BaHSO}_{4}$ and ${O}_{2}$
C ${BaSO}_{4}, {H}_{2}$ and ${O}_{2}$
D ${BaSO}_{4}$ and ${H}_{2}{O}_{2}$

Correct answer

D. ${BaSO}_{4}$ and ${H}_{2}{O}_{2}$

Step-by-step solution

Acidifying barium peroxide and removing excess water by evaporation under reduced pressure gives hydrogen peroxide.

${BaO}_{2} . 8{H}_{2}{O}_{\left(s\right)} + {H}_{2}{SO}_{4\left(aq\right)} \to {BaSO}_{4\left(s\right)} + {H}_{2}{O}_{2\left(aq\right)} + 8{H}_{2}{O}_{\left(l\right)}$

This is a common method to prepare hydrogen peroxide
