Question

The ratio of osmotic pressure of a 1:1 electrolyte AB to that of a non electrolyte solute of same concentration is

• A. 2:1
• B. 0.1:3
• C. 1:1
• D. 0.5:1

Answer 1

The correct option is A

2:1

Van’t Hoff factor of 1:1 electrolyte is 2 since it dissociates into two ions. van’t Hoff factor of a non electrolyte is 1 since it does not dissociate into ions. Hence ratio of osmotic pressure will be 2:1
