A pure sample of water boils at $100\,^{\circ}\text{C}$ and solidifies at $0\,^{\circ}\text{C}$. For a sample of aqueous sodium chloride, what are the boiling point and freezing point?
- Aboiling point $98\,^{\circ}\text{C}$, freezing point $-2\,^{\circ}\text{C}$
- Bboiling point $98\,^{\circ}\text{C}$, freezing point $2\,^{\circ}\text{C}$
- Cboiling point $102\,^{\circ}\text{C}$, freezing point $-2\,^{\circ}\text{C}$
- Dboiling point $102\,^{\circ}\text{C}$, freezing point $2\,^{\circ}\text{C}$
