Question
Why is boiling point of 1 M NaCl solution more than that of 1 M glucose solution?
Advertisements
Solution
Because the van't Hoff factor of 1 M NaCl (2) solution is bigger than that of 1 M glucose (1) solution, boiling point is directly proportional to molality and van't Hoff factor. As a result, the boiling point of 1 M NaCl is higher than that of 1 M glucose solution.
