Definition of Pure Substances and Mixtures

Pure substances are substances that contain only one type of particle and are free of any mixing. To mention a few, pure substances include gold, silver, iron, and aluminium. Pure substances can be split into two groups based on their chemical composition: elements and compounds.

The term “mixture” refers to a compound that contains two or more chemical substances that have not been chemically mixed. When the mixture is in the form of a colloid, suspension, or solution, it is a physical combination of two or more substances in which the individual components’ identities are preserved. Salt and water solutions, sugar and water solutions, air, different gases, and so on are examples of mixtures.
