Question

which of the following has higher boiling point and why.-0.1M NaCl or 0.1M GLUCOSE

Answer 1

NaCl is an electrolyte, so it will dissociate completely to give ions in the solution. Magnitude of any colligative property is directly proportional to the number of particles in the solution. Hence boiling point will , definitely be elevated in greater extent. Glucose is non electrolyte non volatile solute,so it will not dissociate in it's solution. Thus NaCl solution will have greater boiling point than that of glucose solution.
