Question

Which of the following aqueous molal solution have highest freezing point? (A) Aluminium sulphate (B) Barium chloride (C) Potassium bromide (D) Urea

Tardigrade Admin · Accepted Answer

KBr = K ++ Br -=2 ions BaCl 2= Ba 2++2 Cl -=3 ions Al ( SO 4)3=2 Al 3++3 SO 42-=5 ions So, urea is not ionized and hence, it is shows highest freezing point.

Q. Which of the following aqueous molal solution have highest freezing point?

Aluminium sulphate

Barium chloride

Potassium bromide

Urea

$K B r = K^{+} + B r^{-} = 2$ ions

$B a C l_{2} = B a^{2 +} + 2 C l^{-} = 3$ ions

$A l (S O_{4})_{3} = 2 A l^{3 +} + 3 S O_{4}^{2 -} = 5$ ions

So, urea is not ionized and hence, it is shows highest freezing point.
