Mixture

A mixture is a combination of two or more substances that are not chemically bonded to each other. The components of a mixture retain their individual properties and can usually be separated by physical means. Mixtures can be classified into two main categories: 1. **Homogeneous Mixtures**: These have a uniform composition throughout. The individual components are not easily distinguishable. Examples include solutions like saltwater or air. 2. **Heterogeneous Mixtures**: These consist of visibly different substances or phases.
