Question

zn (OH)2- pridation
in oxidation numbers ​

Answer 1

Explanation:

Oxidation numbers for Zn OH 2

Starting with the common grouping of a hydroxyl (OH) as O−2,H+1 for a net charge of -1. That gives a total of -4 charge for the four OH groups. If the whole molecule has a charge of -2, the Zn must be Zn+2 . Checking the Periodic Table, this is a highly likely oxidation state (giving up its 4s electrons).
