What are Mixtures and Solutions? A MIXTURE is a combination of two or more substances that are not chemically united and do not exist in fixed proportions to each other. Most natural substances are mixtures.In the graphic on the left there are four substances - water, alcohol, oil, and food color dye. MIXTURES PURE COMPOUNDS A mixture can be physically separated into pure compounds or elements. A pure compound has a constant composition with fixed ratios of elements. Just about everything that you can think of is probably a mixture. Even the purest of materials still contain other compounds as impurities.Although it is almost physically impossible to isolate absolutely pure substances, a substance is said to be pure if no impurities can be detected using the best available analytical techniques. Mixtures may exhibit a changing set of physical properties.For example, mixture of alcohol and water boils over a range of temperatures.Physical properties such as boiling point or melting point of pure substances are invariant.For example, pure water boils at 100 degrees C

I wish you was a little more specific... But in chemistry a mixture is adding a solute to a solvent.. It can either be heterogeneous or homogeneous.. Homo means its uniform throughout and you can't see the the particles with the naked eye, like kool aid. Hetero you can see it, like a mixture of oil & water. Hoped this helps
