How do the boiling point and freezing point of a solution of water and calcium chloride at standard pressure compare to the boiling point and freezing point of water at standard pressure?
1. Both the freezing point and boiling point of the solution are higher.
2. Both the freezing point and boiling point of the solution are lower.
3. The freezing point of the solution is higher and the boiling point of the solution is lower.
4. The freezing point of the solution is lower and the boiling point of the solution is higher.
