From the colligative properties of solution, which one is the best method for the determination of molecular weight of proteins and polymers?
Multiple Choice Options
- A Osmotic pressure
- B Lowering in vapour pressure
- C Lowering in freezing point
- D Elevation in boiling point
Step-by-Step Verified Solution
Molecular masses of polymers are best
determined by osmotic pressure method . Firstly
because other colligative properties give so low
values that they cannot be measured accurately
and secondly, osmotic pressure measurements
can be made at room temperature and do not
require heating which may change the nature of
the polymer.
