Question

.
Two concentration cells ofAg and Ag electrode in AgNOZ. In first cell concentration of one electrode
is 1 M and other electrode is 0.1 M and emfis 0.06 V. In second cell concentration ofone electrode is
1 M and other electrode is 0.01 M. calculate emf of second cell
(a) 0.12 V
(b) 0.06 V
(c) 0.09 V
(d) 0.16 V​

Answer 1

Answer:

A concentration cell is an electrolytic cell that is comprised of two half-cells with the same electrodes, but differing in concentrations. A concentration cell acts to dilute the more concentrated solution and concentrate the more dilute solution, creating a voltage as the cell reaches an equilibrium.
