Question

Consider a $0.1M$ solution of two solutes $A$ and $B$. $A$ behaves as a non-electrolyte while $80\%$ of $B$ dimerises. Which of the following statement is correct regarding these solutions?

• A. The b.pt of $A$ will be less than $B$
• B. The osomotic pressure of $B$ will be more than thatof $A$
• C. The freezing point of solution $A$ will be less than that of $B$
• D. Boiling points of both solutions will be same.

Answer 1

The correct option is B The osomotic pressure of $B$ will be more than thatof $A$

Correct option (b) The osmotic pressure of B will be more than that of A

Explanation: The concentration of electrolyte, which ionises in water shall be more although 80% of it dimerises
