Overview

A solution is a homogeneous mixture of two or more substances, where one substance (the solute) dissolves in another (the solvent). Solutions are essential in daily life and industrial processes. This chapter explores how solutions form, how their concentration is expressed, and the special properti

Key Concepts

A solution consists of a solute

A solution consists of a solute (the dissolved substance) and a solvent (the medium in which the solute dissolves). The solvent usually determines the

Concentration can be expressed in several

Concentration can be expressed in several ways: Molarity (moles per litre), Molality (moles per kg of solvent), Normality (gram equivalents per litre)

Henry’s Law states that the solubility

Henry’s Law states that the solubility of a gas in a liquid is directly proportional to its partial pressure. Raoult’s Law states that the partial vap

Ideal solutions follow Raoult’s Law exactly

Ideal solutions follow Raoult’s Law exactly, with no heat or volume change on mixing. Non-ideal solutions show deviations—positive (higher vapour pres

These are properties that depend only

These are properties that depend only on the number of solute particles, not their identity. They include relative lowering of vapour pressure, elevat
