Question

Compared to pure water, a salt water solution will have a

Answer 1

Answer:option b. lower freezing point and pressure but higher boiling point

Explanation: by discard c) and d) doesn't have sense because low or Increases boiling and freezing point in the simultaneously.

a) is not correct because if you put salt to boiling watter it will require more heat to get boiling point. Try it

Answer 2

Answer:

lower vapor pressure and freezing point and a higher boiling point

Explanation:

All the properties listed above are colligative properties, they depend on the amount of solute present in a solution.

It is known that a solution has a lower vapour pressure than the corresponding pure solvent due to the presence of a solute. Also the freezing point of a solution is decreased while its boiling point is increased when compared with those of the pure solvent.
