Question

A hypothetical solution Ab is 50% dissociated at freezing point and 80% dissociated at boiling point of solution.If 2 mole of solute is dissolved in 500 g solvent and the difference in boiling point and freezing point of solvent is 100K,then calculate the difference is boiling point and freezing point of solution.(Kb=0.5K kg/mol,Kf=2.0 K kg/mol)

Answer 1

Answer:

Freezing point depression is a colligative property observed in solutions that result from the introduction of solute molecules to a solvent.
