Question

What is the oxidation state of N in Cr(NO3)3?

Answer 1

Answer:

Explanation: NO3- is the nitrate ion, since the overall charge of the anion is -1, you don't need to worry about the O's and the N's as they are unimportant. So since there are three nitrate anions, their total oxidation number is -1 x 3 = -3 so it makes sense that the O.N of the chromium is.

Explanation:

+5

For example, in NO3– the nitrogen is assigned an oxidation number of +5 and each oxygen an oxidation number of –2
