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

Oct 22, 2015

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

#### Explanation:

$1 + B {r}_{O N} - 6 = 0$. $B {r}_{O N} = V +$. This is not the maximum oxidation number of bromine available. What is the oxidation number of bromine in $H B r {O}_{4}$?
