A mixture is a combination of two or more substances that are physically combined but not chemically bonded. Each substance in a mixture retains its own chemical properties and can be separated by physical means. Mixtures are classified based on their composition and properties into two main types: homogeneous and heterogeneous mixtures.

Types of Mixtures

Homogeneous Mixtures

Homogeneous mixtures have a uniform composition throughout. The components are evenly distributed, and the mixture appears as a single phase. Examples include solutions like salt water, sugar dissolved in water, and air.

Solutions: Solutions are a common type of homogeneous mixture where one substance (solute) is dissolved in another (solvent). The particles are at the molecular or ionic level and cannot be seen with the naked eye. Examples include salt water, vinegar, and alloys like brass (a mixture of copper and zinc).

Characteristics of Homogeneous Mixtures

Uniform composition.

Components are not visibly distinguishable.
