Question

What are the variable oxidation numbers of oxygen??

#Chemistry

Answer 1

The oxidation state of oxygen in its compounds is -2, except for peroxides like H2O2, and Na2O2, in which the oxidation state for O is -1.

Answer 2

$\huge\bold{\mathbb{QUESTION}}$

What are the variable oxidation numbers of oxygen??

$\huge\bold{\mathbb{ANSWER}}$

The oxidation state of Oxygen is usually $\sf -2.$

$\Large \implies$ $\sf CO_{2}$

$\:$

In case of peroxides, Oxygen has the oxidation state of $\sf -1.$

$\Large \implies$ $\sf H_{2}O_{2}$

$\:$

For superoxides, the oxidation state of Oxygen is $\sf -{\Large{\frac{1}{2}}}.$

$\Large \implies$ $\sf KO_{2}\:,$ $\sf RbO_{2}$

$\:$

In some cases, oxygen has an oxidation state of $\sf +2.$

$\Large \implies$ $\sf OF_{2}$

$\:$

And in some cases, oxygen also has an oxidation state of $\sf +1.$

$\Large \implies$ $\sf O_{2}F_{2}$
