$2.0$ molal aqueous solution of an electrolyte $X_{2} Y_{3}$ is $75 %$ ionised. The boiling point of the solution a $1 a t m$ is $(K_{b (H_{2} O)} = 0.52 K k g m o l^{- 1})$

Options:

Answer:

Solution:

$X_{2} Y_{3} (a q) \to 2 X^{3 +} (a q) + 3 Y^{2 -} (a q)$

$n = 5$

$Δ T_{b} = i K_{b} . m = (1 + 4 α) K_{b} m$

$= (1 + 4 \times 0.75) \times 0.52 \times 2$

$= 4.16; T_{b} = 373 + 4.16 = 374.76$
