Question

What is oxidation number of ammonium in ammonium ion?

Answer 1

Explanation:

In this case, we know the oxidation number for H is +1. Then set this value equal to the overall net charge of the ion. Our equation now looks like this: 1(4) = 1, You use the multiplier of 4 to indicate that the ammonium ion has 4 hydrogen. Thus, the oxidation number for Nitrogen is -3.
