AB2 is 10% dissociated in water to A2+ and B−. The boiling point of a 10.0 molal aqueous solution of AB2 is ______°C. (Round off to the Nearest Integer).
[Given: Molal elevation constant of water Kb = 0.5 K kg mol−1 boiling point of pure water = 100°C]
Assertion (A): Elevation in boiling point is a colligative property.
Reason (R): The lowering of vapour pressure of solution causes elevation in boiling point.
