Question

1. Compared to pure water, a salt water solution will have a

lower vapor pressure and freezing point and a higher boiling point.

higher freezing point and a lower vapor pressure and boiling point.

lower vapor pressure, freezing point and boiling point

higher vapor pressure, freezing point and boiling point.

The freezing point of a 0.500 M solution of sugar and a 0.500 M solution of KCl in water would be the same.

lower vapor pressure and freezing point and a higher boiling point.

higher freezing point and a lower vapor pressure and boiling point.

lower vapor pressure, freezing point and boiling point

higher vapor pressure, freezing point and boiling point.

The freezing point of a 0.500 M solution of sugar and a 0.500 M solution of KCl in water would be the same.

Explanation / Answer

1 Lower freezing point , lower vapour pressure and higher boiling point

2. False : freezing point of KCl solution will be less as it dissociates into two ions, and lowering in freezing point is a colligative property
