Question

A sample of water contains 12% w / w MgSO 4 ​ and 9.5% w / w MgCl 2 ​ . If the sulphate dissociates to 80% extent and chloride to 60% extent then calculate the boiling point of the solution. Given: K b ​ [ H 2 ​ O ] = 0.785 K − k g / m o l − 1 ] . [Express your answers in Kelvin scale.]

Concepts: Boiling point elevation, van't Hoff factor, molality. Calculation: Δ T b ​ = i K b ​ m . Total i ⋅ m from both salts gives Δ T b ​ = 4 K. T b ​ = 373 + 4 = 377 K.
