Re: Oxidation State
You would find it the same way as a normal compound. Although transition metals can have more than one possible oxidation state, the formula will reflect the oxidation state it is in. For example, if you have FeCl3, then you would find that iron has a +3 oxidation state. Similarly, if you are given FeCl2, you would find that iron has a +2 oxidation state. If you are given the name of the compound, then the oxidation state of the transition metal will be given in roman numerals in parenthesis.

Re: Oxidation State
You solve for the oxidation state by seeing what the rest of the atoms charges are (example Cl is a 1- charge) and the oxidation state of the transition metal will be the charge that will add up to make the charge of the overall molecule.

Re: Oxidation State
To solve at the oxidation state, first look at the charge on the whole compound/molecule. Since transition metals can have different oxidation states, it's important to look at the other atoms its bonded to. For example, if the TM is bonded to one Cl and the whole compound has no charge, then its reasonable to conclude that the TM has a +1 charge. This is because Cl has a -1 oxidation state; to make the compound neutral, you need a positive one charge. Hope this helps!
