coulometric titration
Quick Summary
Coulometric titration is a chemical analysis method where the titrating agent is generated through electrolysis. The amount of substance is determined by measuring the electrical charge (in coulombs) used to produce the necessary amount of the agent. This process is based on Faraday's law, which states a direct relationship between the amount of chemical change and the quantity of electricity used.12
This technique is analogous to volumetric titration but uses electricity to generate the titrant. The substance being analyzed can be measured by either depositing it onto an electrode or by creating a substance in the solution that reacts with the test material.2
