Answer
All ionic compounds are neutral. Because transition metal may have several oxidation states, it may be tricky to determine their charge in a compound. We do this by first determining the charge of the other(s) ion(s) in the compound. Usually, we will have only anions. When we have determined the charge of everything but the transition metal, we can add the charges and then find a number that would make the net charge equal to zero. This last number is the charge of the transition metal.
