Coulometry - Wikipedia
Coulometry is the measure of charge, thus named after its unit the coulomb. Michael Faraday, known for his work in electricity and magnetism, made critical contributions to the field of electrochemistry. He discovered the laws of electrolysis, and in his recognition is the eponym of the Faraday constant.
Coulometry Definition & Meaning - Merriam-Webster
The meaning of COULOMETER is an instrument of chemical analysis that determines the amount of a substance released in electrolysis by measurement of the quantity of electricity used.
11.3: Coulometric Methods - Chemistry LibreTexts
Coulometry is based on an exhaustive electrolysis of the analyte. By exhaustive we mean that the analyte is completely oxidized or reduced at the working electrode or that it reacts completely with a reagent generated at the working electrode.
24.1: Introduction to Coulometry - Chemistry LibreTexts
2022年10月26日 · Coulometry is based on an exhaustive electrolysis of the analyte. By exhaustive we mean the analyte is oxidized or reduced completely at the working electrode, or reacts completely with a reagent generated at the working electrode.
Coulometry - an overview | ScienceDirect Topics
Coulometry is an electrochemical technique, related to amperometry, where the amount of charge (coulombs) passing between two electrodes is measured. The amount of charge passing between the electrodes is directly proportional to oxidation or reduction of an electroactive substance at one of the electrodes.
Electroanalytical methods - Wikipedia
Coulometry uses applied current or potential to convert an analyte from one oxidation state to another completely. In these experiments, the total current passed is measured directly or indirectly to determine the number of electrons passed. Knowing the number of electrons passed can indicate the concentration of the analyte or when the ...
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). The quantity of the material to be analyzed can be determined directly by
Definition of coulometry - Chemistry Dictionary
What is a Coulometry? 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 titration and requires no chemical standards or calibration .
24: Coulometry - Chemistry LibreTexts
There are two forms of coulometry: controlled-potential coulometry, in which we apply a constant potential to the electrochemical cell, and controlled-current coulometry, in which we pass a constant current through the electrochemical cell.
Coulometry - (Analytical Chemistry) - Vocab, Definition ... - Fiveable
Definition. Coulometry is an electroanalytical technique used to measure the amount of substance that is oxidized or reduced during an electrochemical reaction by measuring the total electric charge passed through the system.
