Coulometry is based on the measurement of
Correct answer: A. Electrical current
- A. Electrical current
- B. Electrical potential
- C. Electrical conductance
- D. Dielectric constant
Explanation
Coulometry is an analytical technique where the quantity of a substance is determined by measuring the total electric charge (in Coulombs) required to completely electrolyze it. This is based on Faraday's laws of electrolysis.

About Analytical Chemistry
Analytical chemistry identifies and measures substances using separation and instrumental methods. Chromatography is studied through stationary and mobile phases, retention and Rf values, while spectroscopy connects absorption of electromagnetic radiation with molecular structure and supports qualitative and quantitative analysis through techniques such as UV-visible and infrared spectroscopy.
