Answer to Question #154530 in Electrical Engineering for Nisarga D P

Question

A concentration cell was constructed by immersing two silver electrodes in 0.05 M and 1M AgNO₃ Solutions. Give the cell representation write the cell reaction and calculate the emf of the cell

Answer 1

The cell representation: Ag¹⁺ I Ag⁰ I Ag⁺¹ I Ag⁰

The cell reactions: A(-) : Ag⁰ = Ag⁺¹ + 1e

C(+) :Ag¹⁺ +1e = Ag⁰

To find the EMF of a concentration element, you must use the following formula

$E = \frac{RT}{F}Xln\frac{C1}{C2}$

c1>c2

Therefore,E = 0.08 V
