Calculate the oxidation number of Ni ion `[Ni (H_(2)O_(6))_(6)]^(2+)]`

1.	Calculate the oxidation number of Ni ion `[Ni (H_(2)O_(6))_(6)]^(2+)]` .
Answer» Oxidation number is calculated as follows Charge on complex ino` = +2` Let charge on `Ni =x` Charge on `H_(2)O=O` `implies x + 6 xx (0) = + 2` `implies x = 2+` Hence oxidation number of `Ni is II .
