Question

Out of two $0.1$ molal solutions of glucose and of potassium chloride, which one will have a higher boiling point and why?

Answer 1

Given that the concentration of both the solution (potassium chloride and glucose) is same than 0.1 molal solutions of potassium chloride will have a greater boiling point elevation than glucose solution as it depends on the number of ions present in solution. Since $NaCl$ is an ionic compound it will produce 2 ions in the solution while glucose is a covalent compound and it will remain as such.
