Coulometry and Electrical Charge Analysis

Coulometry is an analytical method that finds the amount of an analyte by measuring the electrical charge needed for its complete electrolysis. It is known for being rapid, accurate, and precise. Unlike many other methods, it does not require analytical standards.

Coulometry uses the amount of electrical charge needed to fully electrolyze an analyte, to determine its quantity without requiring any analytical standards.

The total charge that is passed during electrolysis is related to the amount of analyte by Faraday's laws of electrolysis.

For efficient coulometric measurements, a charge equ...
