Why neutralization is not a redox reaction?

Question

how do we define? More examples needed. THX

A redox reaction is a reaction involving transfer of electrons.

Oxidation is a process in which a substance loses electrons and there is an increase in oxidation number.

Reduction is a process in which a substance gains electrons and there is a decrease in oxidation number.

Both oxidation and reduction must occur to make up a redox reaction.

For neutralization,

( H+ ) + ( OH - ) --- > H2O

The oxidation number of H remains +1 throughout and the oxidation number of O remains -2 throughout. Hence it is not a redox reaction.

Hope it helps.

Answer 2

It is wrong to think that a redox reaction must involve the transfer of elections!!

The converse is true however.

A redox reaction can be defined as this is a a chemical reaction in which at least one substance is oxidized and one is reduced.

Oxidation: Increase in oxidation number.

Reduction: Decrease in oxidation number.

eg. C + O2 -----> CO2

It does not involve the transfer of electrons!!

The O.N. of C increase from 0 to +4 and that of O decreases from 0 to -2!!

Neutralization is not a redox reaction because the oxidation numbers of all the species in the reaction do not change!!
