What is the oxidation state of the K atom in KClO4?
Rules to remember when trying to find out the oxidation state of an element:
(1) The total charge of a stable compound is always equal to zero (meaning no charge).
For example, the
(2) If the substance is an ion (either there is a positive or negative charge) the total oxidation state of the ion is the charge (i.e. oxidation state of
(3) All elements from Group 1A has an oxidation state of +1 (e.g.
(4) Oxygen always have a charge -2 except for peroxide ion (
(5) Hydrogen always have a charge of +1 if it is bonded with a non-metal (as in the case of
