oxidation states

Postby dtolentino1E » Sat Nov 23, 2019 9:33 am

how do i find the oxidation state of a transition metal? so far, i've been confusing it with formal charge, but i know the two are different

To find the oxidation state, you need to figure out the oxidation states of the other atoms in the molecule. For example in NiCl2, you know that each Cl is -1. Since the overall molecule has a neutral charge, Ni must be +2 to balance the two -1 for the Cl's.

You should usually look at the anions first (especially if the cation is a transition metal) and then determine the oxidation state of cation since anion charges are usually the same (e.g. oxygen always has 2- state)
