The osmotic pressure of a non-aqueous solution is measured by

A

Berkeley and Hartley method

B

Pfeffer's method

C

Morse and Frazer method

D

Townend's method

Text Solution

Verified by Experts

The correct Answer is:
D
First three methods involve use of `Cu_(2)Fe(CN)_(6)` as semi-permeable membrane which will be dissolved in non-aqueous solvent and thus only Townend's method having semi-permeable membrane of powdered glass and clay can be used to determine the osmotic pressure of non-aqueous solutions.
