For complex ions, the oxidation state on the metal is simply the charge on the metal, and the coordination number is the number of ligands surrounding the metal.
00:13
So for the first one, we have 6h2os.
00:17
The complex ion has a 3 plus charge.
00:20
The waters are not charged, so the 3 plus charge must be solely on the metal, so its oxidation state then is 3 plus.
00:28
The coordination number is 6 because there are 6 ligands.
00:32
Surrounding six waters surrounding the metal.
00:37
For the next one, we have this complex ion with a charge of minus 1.
00:44
Ammonia has no charge.
00:46
Chloride has a three minus charge, or one minus charge...
