Why does NaCI solution freeze at a temperature lower than the freezing point of water ?

Addition of impurity into water lowers the freezing point of water.

Addition of impurity into water lowers the freezing point of water.

Addition of impurity into water lowers the freezing point of water.

Why does sodium chloride solution freeze at a lower temperature than water?

Why NaCl solution freezes at lower temperature than water but boils at hig' er temperature ?

Sodium chloride solution freezes at a lower temperature but boils at a higher temperature than water. Explain.

Explain with vapour pressure-temperature curves that the freezing point of a solvent is lowered by dissolving a nonvolatile solute into it. Give reason for such lowering of freezing of solvent
