Question

X is dissolved in water.
maximum boiling point is observed when x is (0.1 M each)
1.CaSO4
2.BaCl2
3.NaCl
4.urea

Answer 1

The right answer is b) 0.1 BaCl2 has the highest boiling point.

Explanation :-

The Barium chloride will be

0.1 . mole. L^-1 with respect to

Ba^2+ but

0.2 mol. L ^-1 with respect to

Cl-.

Since, Barium chloride solution contains the greatest number of solute particles, we would predict that this solution should exhibit the highest boiling point.

Answer 2

Correct answer is:- 2.BaCl2
