A redox reaction consists of oxidation and reduction half reactions. There is a loss of electrons in oxidation and the species which loses elecrons is sreducing agnet.Its oxidation number increases during oxidation. Similarly there is a gain of electrons during reduciton and the species wlhih gains electrons is an odidsing agent. thhe species which gains electrons is an aoxidising agent its oxidstion number decreases during reduction .The number of electrons released during oxidation is equal to number of electrons gained dunring reduciton
The reation:
`2H_(2)O(L)rarr4H^(+)(aq)+O_(2)+4e^(-)` is

A

an oxidation reaction

B

a reduction reaction

C

a redox reaction

D

a hydrolysis reaction

Text Solution

Verified by Experts

The correct Answer is:
A
It is an oxidation reaction as there is loss of electrons
