D.
sodium sulphate and hydrogen peroxide
Answer :
sodium sulphate and hydrogen peroxide
Solution :
\[\underset{\begin{smallmatrix}
\text{Sodium} \\
\text{peroxide}
\end{smallmatrix}}{\mathop{N{{a}_{2}}{{O}_{2}}}}\,+{{H}_{2}}S{{O}_{4\left( \text{dil}\text{.} \right)}}\to \] \[\underset{\begin{smallmatrix}
\text{Sodium} \\
\text{sulphate}
\end{smallmatrix}}{\mathop{N{{a}_{2}}S{{O}_{4}}}}\,+\underset{\begin{smallmatrix}
\text{Hydrogen} \\
\text{peroxide}
\end{smallmatrix}}{\mathop{{{H}_{2}}{{O}_{2}}}}\,\]
