Answer: lower freezing point and a higher boiling point than water

Explanation:

Addition of a non volatile solute leads to elevation in boiling point and depression in freezing point.

This increase in boiling point arises because particles of the non-volatile solute occupy the surface of solution due to which solvent particles can not escape out of the solution. Hence, high amount of heat is required for the solute particles to escape out of the solution. Therefore, an increase in boiling point will occur.

Also as vapor pressure of solution becomes less, the freezing point gets depressed as freezing point is the temperature at which vapor pressure of solid becomes equal to the vapor pressure of solution.

Thus at standard pressure when NaCl is added to water,the solution will have a lower freezing point and a higher boiling point than water
