Question

In reaction

$S{O}_2$ + $H_{2}S$ $\to$ $2H_{2}O$ + $3S$

the reducing agent is –

• A. $S{O}_2$
• B. $H_{2}S$
• C. $H_{2}O$
• D. $S$

Answer 1

The correct option is B

$H_{2}S$

In reaction $S{O}_2$ + $H_{2}S$ $\to$ $2H_{2}O$ + $3S$,
the reducing agent is $H_{2}S$ as it donates hygrogen to $S{O}_2$.
