Consider the following relations for emf of an electrochemical cell (i) EMF of cell = (Oxidation potential of anode) - (Reduction potential of cathode)
(ii) EMF of cell - (Oxidation potential of anode) + (Reduction potential of cathode)
(iii) EMF of cell = (Reductional potential of anode) + (Reduction potential of cathode)
(iv) EMF of cell = (Oxidation potential of anode) - (Oxidation potential of cathode)
Which of the above relations are correct?

A

(iii) and (i)

B

(i) and (ii)

C

(iii) and (iv)

D

(ii) and (iv)

Text Solution

Verified by Experts

The correct Answer is:
D
EMF of a cell Reduction potential of cathode
- Reduction potential of anode
=Reduction potential of cathode + Oxidation potential of anode
=Oxidation potential of anode-Oxidation potential of cathode.
