Question

$C{l}_2+H_{2}S\to 2HCl+S$, In the reaction, oxidation state of chlorine changes from.

• A. Zero to $-1$
• B. $1$ to zero
• C. Zero to $1$
• D. Remains unchanged

Answer 1

The correct option is A Zero to $-1$

In ${Cl}_2$ oxidation state is (0) and in $HCl$ oxidation state of chlorine is (-1). So oxidation state of chlorine changes from 0 to -1.
