At`25^(@)C` the highest osmotic pressure is exhibited by `0.1M` solution of

Options

A. `CaCl_(2)`
B. `KCl`
C. glucose
D. urea

Answer

A

Explanation

`CaCl_(2)` is an electrolyte and dissociates to give three ions as
`CaCl_(2)rarr Ca^(2+)+2Cl^(-)`
While KCl given two ions and glucose and urea are non-electrolytes , so remains undissociated. As osmotic pressure is a colligative property (i.e. depend only on number of particles), so highest for `CaCl_(2)`.
