Question

At 25°C, the highest osmotic pressure is exhibited by 0.1 M solution of
(a) CaCl₂
(b) KCl
(c) glucose
(d) urea

Answer 1

In solution, CaCl2 gives three ions, KCI gives two ions while glucose and urea are covalent molecules so they do not undergo ionisation.

Since osmotic pressure is a colligative property and it depends upon the number of solute particles (ions), therefore, 0.1 M solution of CaCl2 exhibits the highest osmotic pressure.
