Given information
Given redox reaction:
Step-by-step explanation
We know that, when oxidation and reduction reaction takes place simultaneously in a chemical reaction, they are called redox reactions. There are two electrodes i.e. cathode where reduction occurs and the other one is anode where oxidation occurs.
When oxidation occurs, there is an increase in the oxidation number of the species.
When reduction occurs, there is a decrease in the oxidation number of the species.
In the given redox reaction,
is converted to by releasing two electrons. This is an oxidation half cell reaction that is taking place at the anode.
is converted to water in presence of an acid catalyst. This is a reduction half cell reaction that is taking place at the cathode.
Oxidation reaction at the anode:
Reduction reaction at the cathode:
