Definition: A mixture consists of two or more substances combined together without a chemical reaction.
Types:
Homogeneous Mixtures: Uniform composition (e.g., saltwater).
Heterogeneous Mixtures: Distinct components (e.g., salad).
Physical Properties: Each component retains its own physical properties, such as boiling point and density.
Separation: Mixtures can be separated by physical methods (e.g., filtration, distillation).
Examples:
Homogeneous: Air, vinegar.
Heterogeneous: Oil and water, gravel.
Applications: Mixtures are used in everyday life and industries, such as food production and pharmaceuticals.
No Fixed Ratio: The components of a mixture can be present in varying proportions.
Reversibility: Many mixtures can be reversed to obtain the original substances.
