determine whether each of the examples represents a colligative property or a non-colligative property.
Is the property described colligative or non-colligative?
Answer:
Colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent molecules in a solution, but not on the nature of the solute particles. On the other hand, non-colligative properties are properties that are dependent on the chemical identity of the solute particles.
Examples of colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and osmotic pressure. These properties are directly proportional to the concentration of solute particles in the solution.
Non-colligative properties, on the other hand, include characteristics such as color, taste, and chemical reactivity, which are specific to the individual solute particles in the solution and do not depend solely on the concentration of solute particles.
Therefore, in order to determine whether a property is colligative or non-colligative, one needs to consider whether the property is affected by the number of solute particles regardless of their identity, or if it is specific to the nature of the solute particles themselves.
