Chapter 4: Problem 18

Which of the following is a colligative property? (a) Molecular weight (b) Osmotic pressure (c) Parachor (d) Surface tension

Short Answer

Expert verified
Out of the given options, Osmotic pressure (b) is a colligative property.

Step by step solution

01

Analyze all options

Each option should be analyzed individually. Molecular weight is not a colligative property, it is the weight of a molecule and is used in stoichiometry. Parachor is a property related to the surface tension of a liquid and its specific volume. Surface tension itself is a property of liquids that arises due to forces of attraction between the liquid molecules, preventing the liquid from being easily pulled apart.
02

Identify the colligative property

Osmotic pressure is a colligative property. It is the pressure required to prevent solvent from passing into a given solution by osmosis. Osmotic pressure, like other colligative properties, depends on the number of solute particles dissolved in the solvent, not on the nature of the particles.
