Question

A solution containing (10 ~g ) of an electrolyte ( AB ₂ ) in (100 ~g ) of water boils at (100.52^ C ). The degree of ionization of the electrolyte (( ) ) is _______ ( 10⁻¹ ). (nearest integer) [Given : Molar mass of ( AB ₂=200 ~g ~mol ⁻¹, ~K _ b ) (molal boiling point elevation const. of water) (=0.52 ~K ~kg ~mol ⁻¹ ), boiling point of water (=100^ C ; AB ₂ ) ionises as ( . AB ₂ A ²⁺+2 ~B ⁻ ] )
