Question

In the reaction $2H_2{O}_2\to 2H_{2}O+O_2$ oxidation state of oxygen changes as?

• A. Only $-1$ to $-2$
• B. Only $-1$ to zero
• C. Both of the above
• D. $-1$ to$-3$

Answer 1

The correct option is C Both of the above

In $H_2{O}_2$ oxidation of $O$ is $-1$.
In $H_{2}O$ oxidation of $O$ is $-2$ and in $O_2$ oxidation of $O$ is zero.
