The current-voltage characteristics forms the basis of
Correct answer: D. Polarography
- A. Thermal analysis
- B. Potentiometry
- C. Conductometry
- D. Polarography
Explanation
Polarography is a type of voltammetry where the potential of a dropping mercury electrode is varied and the resulting current is measured. The resulting current-voltage curve, or polarogram, provides information about the analyte.

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.
