Oxidation States and Nitrate Ions

The video tutorial explains how to find the oxidation numbers in Sn(NO3)2, a neutral compound. It discusses the oxidation state of tin, a transition metal, and its bonding with the nitrate ion, which has a one-minus ionic charge. The tutorial demonstrates how the oxidation numbers of the nitrogen and oxygen in the nitrate ion add up to the ion's charge. With two nitrate ions, the total oxidation number is minus two, requiring tin to have a plus two oxidation number. This is why the compound is called tin(II) nitrate. Additional resources are provided for further learning.
