COULOMETRY Meaning and
Definition
-
Coulometry is a scientific technique used to measure the quantity of substances undergoing electrochemical reactions. It is based on Faraday's laws of electrolysis and employs the principles of electricity to quantitatively determine the amount of a substance involved in a chemical reaction.
In coulometry, an electric current is passed through a solution containing the substance of interest, causing a redox reaction to occur at an electrode. The amount of substance transformed during this process is directly proportional to the quantity of electricity passed through the system, as stated by Faraday's laws. This relationship allows for accurate determination of the substance's concentration or quantity.
The term "coulometry" is derived from the unit of charge, the coulomb, which measures the amount of electrical charge flowing through a circuit. This technique is commonly used in electrochemistry, analytical chemistry, and various industrial processes where precise measurement of substances is essential. It offers high accuracy and precision, making it particularly useful in quality control and research laboratories.
Coulometry can be performed using different setups, such as potentiostatic or galvanostatic modes, and it often involves the use of specialized electrochemical cells or titration apparatus. The metadata collected during a coulometric analysis can be used to determine the stoichiometry of the reaction, identify unknown substances, or track the progress of a chemical reaction. This technique plays a crucial role in fields such as chemical synthesis, environmental analysis, and the development of new materials.

Etymology of COULOMETRY
The word "coulometry" is derived from the name of the French physicist Charles-Augustin de Coulomb (1736-1806) and the suffix "-metry", meaning the process of measuring or the science of measurement.
Coulometry refers to a quantitative electrochemical method used to measure the amount of a substance involved in a chemical reaction, typically by measuring the electric charge associated with the reaction. The term was coined based on Coulomb's contributions to the fields of electricity and magnetism, especially his work on electric charges and electrical forces.
