Astudent dissolves 4.5 g of sodium chloride (nacl) into 75 g of water (h2o). which of the following statements is correct regarding the resulting solution when it is compared to the pure solvent? both the vapor pressure and the boiling point will increase. the boiling temperature and the freezing temperature will decrease. the freezing temperature will increase and the vapor pressure will decrease. the vapor pressure will decrease and the boiling temperature will increase.

The correct answer is that the vapor pressure will decrease and the boiling temperature will increase.

Explanation:

In the given question, when NaCl is supplemented to water, the vapor pressure of the resulting solution of salt becomes less in comparison to the vapor pressure of the pure water, and the boiling point of the solution of the salt will be more in comparison to the boiling point of pure water. This occurs because of the presentation of salt molecules to water, in which the salt solution requires more temperature for the vapor pressure to become equivalent to the pressure of the atmosphere.
