Question

What is the oxidation state of an individual bromine atom in NaBrO3?

Answer 1

Assign individual oxidation states, oxygen is usually `-II`; sodium ion is `I+`.

Explanation:

`1+ Br_(ON)-6 =0`. `Br_(ON) = V+`. This is not the maximum oxidation number of bromine available. What is the oxidation number of bromine in `HBrO_4`?
