Concept explainers
Interpretation:
The standard reduction potential at 25°C for the half-reaction needs to be identified.
Concept introduction:
A reducing or a reductant is a species that loses electron/s and gets oxidized in the
An oxidizing agent is an agent which gains the electrons and gets reduced within the chemical reaction. It is also recognized as electron acceptor; it is usually in one of its higher probable oxidation states so that it can reduce after accepting electron/s.
Spontaneity of a reaction is dependent on the free energy sign that is
Since,
Here, n = number of electrons involved in reaction and F is Faraday’s constant.
If the value of E° for a reaction is positive, then the reaction occurs spontaneous.
