Question

Which of the following is not a colligative property? osmotic pressure vapor pressure ra g boiling point elevation freezing point depression All of the above are colligative properties Sucrose is a nonvolatile, nonionizing solute in water. Determine the vapor pressure lowering, at 27 degree C. of a solution of 75.0 grams of sucrose, C_12H_22O_11, dissolved in 180. g of water. The vapor pressure of pure water at 27 degree C is 26.7 torr. Assume the solution is ideal. 0.585 torr 0.058 torr 0.572 torr 5.62 torr 0.548 torr

Explanation / Answer

7)

Colligative properties are osmotic pressure, boiling point elevation, freezing point depression and vapor pressure lowering.

So the option that is not a colligative property is (b) vapor pressure raising.
