What is the oxidation number of Br in HBrO2?

Answer 1

Let tho oxidation number of Br=x.The oxidation no of H=+1 and that of o=-2. Thus adding all => 1 + x - 2 = 0 => x - 1 = 0 => x = 1

Thus x comes out to be x = 1.

Answer 2

The oxidation of oxygen is -2, hydrogen is +1, so bromine must be +1.

Answer 3

This is a little bit stong acid. Bromine shows +7 as the oxidation number.

Answer 4

+1 for H

+3 for Br

-2 for O

Answer 5

Br would have a 1+ oxidation #
