What is the oxidation number of bromine in the BrO₃^- ion?

Question

Quizplus · Accepted Answer

The total charge of the ion is (-1) + 1 + 3 + 5 + (-1) + (-1) + 0 = -4. Since the overall charge of the ion is negative, and oxygen typically has an oxidation number of -2, the oxidation number of bromine can be calculated as follows:
(-1) + 1x + 3(-2) + 5x + (-1) + (-1) + 0 = -4
Simplifying the equation, we get:
5x - 5 = -4
5x = 1
x = +1/5
Therefore, the oxidation number of bromine in the ion is +5.
