CONCENTRATION CELL Meaning and
Definition
-
A concentration cell is an electrochemical cell consisting of two half-cells with the same electrode materials but different concentrations of the same electrolyte. It operates based on the principle that when the concentrations of electrolytes are different in two compartments, a potential difference is generated across the electrodes. This potential difference drives the movement of ions, resulting in an electric current.
In a concentration cell, the electrode materials and the electrolyte remain the same, but the concentrations of the electrolyte differ. One half-cell typically contains a higher concentration of the electrolyte, known as the concentrated side, while the other half-cell contains a lower concentration, known as the dilute side. The potential difference that arises due to differences in concentration is known as the concentration potential.
The concentration cell finds widespread applications in various fields, including corrosion studies and measurement of ion activities. For instance, it is employed to measure the pH of a solution by using identical electrodes and different concentrations of an acidic or basic electrolyte. By measuring the voltage generated, the pH of an unknown solution can be determined.
Overall, a concentration cell is an electrochemical cell that uses differences in electrolyte concentration to produce a potential difference across its electrodes. It serves as a valuable tool in understanding and measuring various electrochemical phenomena.

Etymology of CONCENTRATION CELL
The word "concentration cell" is composed of two components: "concentration" and "cell".
The term "concentration" derives from the Latin word "concentratio", which means a gathering together or a mixing. In colloquial usage, "concentration" refers to the action or process of increasing the strength, density, or proportion of a substance by removing or reducing the amount of solvent, diluent, or other unnecessary elements.
In the context of a "concentration cell", the term "cell" refers to a system or device that contains two electrodes immersed in an electrolyte solution. This usage of the word "cell" originates from the resemblance of the device to a small, enclosed compartment or chamber.
In summary, the etymology of the word "concentration cell" relates to the gathering or mixing of different elements (concentration) within a small compartment or system (cell) for electrochemical purposes.
