Concentration Cell Definition, Details, Types, and

Concentration cells can be defined as electrochemical cells that consist of two half-cells wherein the electrodes are the same, but they vary in concentration. As the cell as a whole strives to reach equilibrium, the more concentrated half cell is diluted and the half cell of lower concentration has its concentration increased via the transfer of electrons between these two half cells.

The emf of the cell is 0.118 V at 25 C. Calculate the concentration of hydrogen ions at the positive electrode. Answer: The cell may be represented as: P t ∣ H 2 (1 a t m) ∣ H + ∣ ∣ H + ∣ H 2 (1 a t m) ∣ P t Since this is a concentration cell, E c e l l o = 0.
