WebMay 14, 2014 · The oxidation state of Cr in Cr (H₂O)₆³⁺ is +3. Let's recall some of the rules for calculating oxidation states. • The oxidation state of O is almost always -2. • The oxidation state of H is almost always +1. • The sum of all the oxidation states equals the charge on the ion. If H = +1, then 2H = +2. If O = -2, then 2H + O = +2 - 2 = 0.
