What is the oxidation number of chlorine in LiClO₂?

Question

Quizplus · Accepted Answer

The oxidation number of Li is +1, and the oxidation number of oxygen is -2. Let's assume the oxidation number of Cl is x. Then, we can write the equation:
Li + ClO₂ → LiClO₂
We know that the overall charge of the compound is 0, so we can set up an equation:
Li + x + (-2*2) = 0
Simplifying, we get:
Li + x - 4 = 0
x = +4 -Li
Since Li is +1, Cl must be +3. Therefore, the oxidation number of chlorine in LiClO₂ is +3.
