Question 3 • *25-26 KCS18 Chemistry IC

Suppose that you have 1.0 kg of water. How will the boiling point of the water change if you add 2.0 mol of sucrose?

Answer
A
It will increase.
B
It will decrease.

Explanation

Dissolving sucrose, a nonvolatile solute, raises water’s boiling point. The added sucrose lowers the solution’s tendency to evaporate, so the water must be heated to a higher temperature to boil. Therefore, the boiling point will increase.
