Hydrogen peroxide acts both as an oxidising and as a reducing agent depending upon the nature of the reacting species. In which of the following cases $H_2O_2$ acts as a reducing agent in acidic medium?

$H_2O_2$ is used as:

$H_2O_2$ is a

Electrolysis of $X$ gives $Y$ at anode. Vacuum distillation of $Y$ gives $H_2O_2$. The number of peroxy $(O-O)$ bonds present in $X$ and $Y$ respectively are :

The strength in volumes of a solution containing $30.36 \ g/L$ of $H_2O_2$ is
