Coulometry - Wikipedia
In analytical electrochemistry, coulometry is the measure of charge transfer during an electrochemical redox reaction. [1] It can be used for precision measurements of charge, but coulometry is mainly used for analytical applications to …

Coulometry - an overview | ScienceDirect Topics
Coulometry is an electrochemical method in which the total charge (the number of coulombs) consumed in the redox conversion of an analyte at an electrode is measured. It is not to be confused with colorimetry, the spectroscopic method.
Coulometry | Electrochemical, Titration, Quantitative Analysis
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).
What Is Coulometry? - AllTheScience
2024年5月21日 · Coulometry is a form of quantitative analysis used to determine the concentration of a substance in solution — generally referred to as the analyte — by measuring the amount of electricity required to change the oxidation state of the substance.
Coulometry | 2 | v2 | Modern Methods of Pharmaceutical Analysis, …
Coulometry is an electrochemical assay technique involving complete reduction or oxidation of a chemical species. The titrant employed, directly or indirectly, is the electron. The total titrant transferred is equal to the amount of charge consumed, that is, the integral of current vs. time. Since charge can be directly measured, coulometry ...
Electrolysis Cells for Potentiostatic Coulometry sometimes referred to as coulometric titration in which the titrant is electrons •The electrons may let an analyte reduced or oxidized •The electrons may also produce a species that reacts with the analyte •The calculation of quantity of electricity involved is straight forward •Q = I x t
Definition of coulometry - Chemistry Dictionary
Coulometry is an analytical method for measuring an unknown concentration of an analyte in solution by completely converting the analyte from one oxidation state to another. Coulometry is an absolute measurement similar to gravimetry or …
