What is Mixture?

A combination of two or more substances that are physically combined but not chemically bonded. Mixtures retain the properties of their components and can be separated by physical means. Homogeneous mixtures (solutions) have uniform composition; heterogeneous mixtures do not.

Properties & Characteristics

A mixture is a material composed of two or more substances that are not chemically combined and retain their individual properties. Mixtures are characterised by variable composition (unlike compounds) and can be separated by physical means (distillation, filtration, chromatography, evaporation). Homogeneous mixtures (solutions) appear uniform; heterogeneous mixtures (suspensions, colloids, mechanical mixtures) have distinguishable phases or regions.

Uses & Applications

Mixtures are encountered everywhere: air (N₂, O₂, Ar, CO₂), blood (water, proteins, cells, ions), petroleum (mixture of hydrocarbons), alloys (mixtures of metals), pharmaceuticals (active ingredient in excipient mixture), and in synthetic chemistry (reaction mixtures of starting materials, solvents, and products).

Safety Information

Hazardous mixtures include: explosive mixtures (fuel-air mixtures within LEL-UEL range), toxic mixtures (chlorine + ammonia → chloramine), corrosive mixtures (acids + bases), and persistent environmental mixtures (PCBs, PAHs in contaminated soil). Never mix chemicals without understanding the consequences — unexpected reactions can be dangerous.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
