What are colligative properties? What is the meaning of the word "colligative" in this context?

Short Answer

Expert verified
Colligative properties are those of a solution that depend only on the number of solute particles, not their nature or identity. The term 'colligative' comes from Latin 'colligatus' denoting 'bound together', highlighting how these solute particles collectively influence the properties of the solution.

Step by step solution

01

Understanding Colligative Properties

Colligative properties are characteristics of solutions that depend solely on the concentration of their solute particles, not the type of solute particles. Examples include boiling point elevation, freezing point depression, vapor pressure lowering, and osmotic pressure.
02

Understanding the term 'Colligative'

The word 'colligative' is derived from the Latin 'colligatus,' meaning 'bound together.' It refers to how the solute particles in a solution are 'bound together' and act as a single unit in terms of influencing the solution's properties.
03

Linking the Concepts

Now that we understand both terms separately, let's combine them. Colligative properties depend solely on the number of solute particles because all the particles are 'bound together' in their influence -- regardless of their individual nature or identity. This is why these properties are termed 'colligative'.
