Question

The aqueous solution that has the lowest vapour pressure at a given temperature is (A) 0.1 molal sodium phosphate (B) 0.1 molal barium chloride (C) 0.1 molal sodium chloride (D) 0.1 molal glucose

0.1 m Na 3 PO 4=0.4 m particles which is maximum. So, lowering of vapour pressure will be maximum.

Q. The aqueous solution that has the lowest vapour pressure at a given temperature is

0.1 molal sodium phosphate

0.1 molal barium chloride

0.1 molal sodium chloride

0.1 molal glucose

$0.1 m N a_{3} P O_{4} = 0.4 m$ particles which is maximum.
So, lowering of vapour pressure will be maximum.
