Question

In the reaction $H_{2}S+C{l}_2\to 2HCl+S$, the oxidizing agent is :

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

Answer 1

The correct option is B $C{l}_2$

Chlorine $C{l}_2$ is the oxidizing agent. It oxidizes $H_{2}S$ to $S$.
Note: removal of hydrogen from a molecule is oxidation.
$H_{2}S\stackrel{-H_2}{\to }S$ ...... oxidation.
Addition of hydrogen is reduction.
$C{l}_2\stackrel{H_2}{\to }2HCl$ ...... reduction.
