Question

The oxidation state of oxygen in KO2 is
1) -2
2) -1
3) -4
4) +4

Answer 1

Answer:

2−1

The oxidation number of oxygen in KO2 is 2−1.

Explanation:

Let x be the oxidation number of oxygen in potassium super oxide (KO2). 

The oxidation number of potassium is +1. 

In the neutral molecule, the sum of the oxidation number is 0.

1+2(x)=0 or, x=−1/2

Answer 2

Answer:

-1/2 is the answer of your question
