Presence of a small amount of water in the organic systems can be determined by the _____________ method?
Correct answer: D. Dielectric constant end loss factor
- A. Electrical conductivity
- B. Polarimetry
- C. Emission spectroscopy
- D. Dielectric constant end loss factor
Explanation
Water changes the dielectric constant and dielectric loss factor of an organic liquid substantially, allowing small amounts to be detected electrically. The other listed methods are not the usual direct method for trace water in organic systems.
