Concentration of sugar solution can be determined by the__________________?
Correct answer: C. Polarimetry
- A. Emission spectroscopy
- B. Flame photometry
- C. Polarimetry
- D. Oscillometry
Explanation
Sugar solutions rotate the plane of polarised light, and the angle of rotation is related to concentration, which is the basis of polarimetry. Flame photometry and emission spectroscopy are mainly used for elemental analysis, not routine sugar concentration measurement.
