1 molal aqueous solution of an electrolyte A 2 B 3 is 60 % ionised. The boiling point of the solution at 1 atm is _____ K . (Rounded-off to the nearest integer) [Given K b for H 2 O = 0 . 52 K kg mol - 1 ]

Question

1 molal aqueous solution of an electrolyte A 2 B 3 is 60 % ionised. The boiling point of the solution at 1 atm is _____ K . (Rounded-off to the nearest integer) [Given K b for H 2 O = 0 . 52 K kg mol - 1 ],

ΔT b = iK b m = 1 + 4 α × 0 . 52 × 1 = 3 . 4 × 0 . 52 × 1 = 1 . 768 T b = 1 . 768 + 373 . 15 = 374 . 918 K = 375 K Hence answer is 375
