Question

In the reaction: cl2 + h2o ??? hclo + hcl, the hydrogen is

Answer 1

The answer is neither oxidized nor reduced. It is element chlorine which is both oxidized and reduced in the reaction as shown by the oxidation number of chlorine that is equal 0 in the Cl2 and that is equal to -1 in HCl and +1 in the chlorate(I) ion ClO- in the products.

Answer 2

In the given reaction hydrogen atom is neither oxidised not reduced, because oxidation state is same on both sides.

What is oxidation number?

Oxidation number of any substance gives idea about the number of exchangeable electrons from the outermost shell of the substance.

Given chemical reaction is :

Cl₂ + H₂O → HClO + HCl

In the above equation:

• Oxidation state of hydrogen atom on the left side of the reaction is same as on the right side of the reacttion i.e. +1 so hydrogen atom is neither oxidised nor reduced.
• Oxidation state of chlorine atom changes from 0 to +1 as well as -1 also, means it gets oxidised and reduced also.

So, hydrogen atom neither oxidised nor reduced.
