Oxidation Numbers in Nitrite Ion

This video tutorial explains how to determine the oxidation numbers for each element in the nitrite ion (NO2-). It begins by identifying the oxidation numbers for oxygen, which is typically -2, and then uses the overall charge of the ion to calculate the oxidation number for nitrogen. The tutorial concludes with a recap of the process, emphasizing the use of known oxidation numbers and the ion's charge to find unknown values.
