What is the oxidation number of oxygen in potassium superoxide, KO₂? A) +1 B) 0 C) -½ D) +½ E) -2

Question

Quizplus · Accepted Answer

In KOSB, the oxidation number of K is +1 (group 1 element) and the overall charge of the compound is -1. Since there are two oxygen atoms, x + 2*(-1/2) = -1, where x is the oxidation number of oxygen. Solving for x, we get x = -1/2. Therefore, the oxidation number of oxygen in potassium superoxide is -1/2.
