Question
When sugar is added, what effcts on the boiling and freezing of water is seen?
- Boiling point increases, freezing point increases.
- Boiling point decreases, freezing point increases.
- Boiling point increases, freezing point decreases.
- None of the above
Hint:
Colligative properties.
The correct answer is: Boiling point increases, freezing point decreases.
- There are two colligative properties of a liquid: elevation of boiling point and depression of freezing point.
- Both depend on the concentration of solute added to water.
- When sugar is added to water freezing point decreases and the boiling point increases.
