The property of liquid that is measured by a polarimeter?
Correct answer: C. Optical activity
- A. Conductance
- B. Refractive Index
- C. Optical activity
- D. Change in volume
Explanation
Optical activity is the ability of a substance to rotate planepolarized light, typical for chiral compounds. A polarimeter measures the angle of rotation, which indicates the concentration or purity of the optically active substance

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.
