Which solution will have a higher boiling point? which will have a lower Freezing point? exain why for each. A)0.2 M PbCl2 B) 0.2 M NaCl
The answer will be 2- lower vapor pressure, higher boiling point and lower freezing point.
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.
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
