Question

oxidation number of Cl in HclO2?​

Answer 1

+3

Example #8: What is the oxidation number of Cl in HClO2? The oxidation number of H = +1. There is 1 H atom: (1)(+1) = +1 The oxidation number of O is -2. There are two O atoms: (2)(-2) = -4 Therefore, the oxidation state of Cl is +3.

Answer 2

Answer:

Consider the oxidation number of Cl be y.

Oxidation state of Hydrogen = +1.

Oxidation state of Oxygen = -2.

=> 1 + y - 4 = 0

=> y = 3  

Explanation:

• An atom's oxidation state (also known as its oxidation number) in a chemical compound gives information on how many electrons were lost from it and, as a result, describes the degree of oxidation of the atom.
• The imagined charge that an atom would carry if all of its links to other atoms were entirely ionic in nature can be used to determine an atom's oxidation state.
• For instance, if both of the carbon-oxygen double bonds were entirely ionic, the carbon atom's potential charge would be equal to +4, the oxidation state of carbon in CO2 would be +4. (Each oxygen atom would hold a charge of -2 since oxygen is more electronegative than carbon).
