coulometry

in analytical chemistry, method for determining the quantity of a substance, based on the strict proportionality between the extent of a chemical change and the quantity of electricity involved (Faraday's law). The quantity of the material to be analyzed can be determined directly by depositing the substance on an electrode or by generating electrolytically in the solution a known amount of a substance that will react with the test material. The latter method is analogous to volumetric titration.
