Question

$H_{2}S{O}_4$ cannot be used to dry up $H_{2}S$ because it oxidises $H_{2}S$ to $S{O}_2$ and $S$.
If true enter 1, else enter 0.

• A. 1

Answer 1

The correct option is A 1
$H_{2}S{O}_4$ cannot be used to dry up $H_{2}S$ because it oxidizes $H_{2}S$ to $S{O}_2$ and $S$.
The reaction is as follows:
$H_{2}S{O}_4+H_{2}S\to S{O}_2+S+2H_{2}O$.
$H_{2}S$ can be dried by passing through $CaC{l}_2$ or $P_2{O}_5$.
