Question

The oxidation state of chlorine in HCLO4? ​

Answer 1

There is one H atom: (1)(+1) = +1 The oxidation number of O is -2. There are four O atoms here: (4)(-2) = -8 Therefore, the oxidation state of Cl is +7. NOTE: The maximum positive oxidation number for chlorine is +7, the same as its group number (VII)

Answer 2

The oxidation state of chlorine in HCLO4 is +7.

Explanation:

• HClO4 is still neutral because we can look at the formal charges in the Lewis structure to determine the charge of HClO4.
• The Cl atom would have three double bonds with three oxygen atoms and one single bond with OH, causing the formal charge of Cl to be 0.
• An oxidation state is a number that is assigned to an element in a chemical combination.
• This number represents the number of electrons that an atom can gain, lose or share when chemically bonding with an atom of another element.
