Which of the following colligative properties can provide molar mass of proteins, polymers and colloids with greater precision?
- A Elevation in boiling point
- B Depression in freezing point
- C Osmotic pressure
- D Relative lowering of vapour pressure
Answer & Solution
Correct Answer
(C) Osmotic pressure
Step-by-step Solution
Detailed explanation
Among the given colligative properties, osmotic pressure can provide molar mass of protcins, polymers and colloids with greater precision. Because for these substances, the value of other given colligative properties are too small to be measured. Secondly, this method has the advantage i.c., this use molarities instead of molalities.
