Different molecular sizes is the differences that a chromatography rely on in order to separate out parts of a solution. All chromatographic systems rely on the fact that a substance placed in contact with two immiscible phases one moving and one stationary phase will equilibriate.

Chromatography works because of differences in the properties of molecules in materials. If a solvent used, the solvent depends on the material to be separated. Liquid and gas mixtures can be pushed or pulled through a material that absorbs the molecules as they pass through.

Distillation takes advantage of differences in boiling points. Evaporation removes a liquid from a solution to leave a solid material. Filtration separates solids of different sizes.

Ion exchange chromatography separates the components of a mixture based on their charge, in addition to or instead of their size. In essence, positively (cations) or negatively (anions) charged ions are separated using different stationary phases and different pH mobile phases.

Mixtures can be physically separated by using methods that use differences in physical properties to separate the components of the mixture, such as evaporation, distillation, filtration and chromatography.

A solution is a homogeneous mixture of two or more components in which the particle size is smaller than 1 nm. Common examples of solutions are the sugar in water and salt in water solutions, soda water, etc. In a solution, all the components appear as a single phase.

Mixtures are just as important as elements, compounds or alloys. In fact, the air that you are breathing right now is a mixture of oxygen, nitrogen and some lesser gases! Mixtures are used in many processes, including steel manufacturing, the chemical industry and many others.

Not necessarily, mixture may comprise of one or more form of matter. Separation of mixture into its individual components may be useful it depends upon whether component we are separating is of use to us or not.

1: Mixtures are useful when you want to combine elements of multiple materials into one product. I.E. you want to rehydrate AND replenish electrolytes so you mix salt in water (or buy Brondo.) 2: Mixtures allow you to dilute a pure ingredient into a product with less ingredient per unit volume.

Solution: a homogeneous mixture of two or more substances. Example: water, sugar, flavor mixture (Coke). The substances are physically combined, not chemically combined or bonded to each other. Solvent: usually the substance in the greater amount.

Mixtures are materials that contain two or more chemical substances dispersed among each other (mixed together). Solutions are homogenous mixtures: particles of one substance (the solute) are mixed together with the particles of another substance (the solvent) – eg salty water.

A Tea is a solution of compounds in water, so it is not chemically pure. It is usually separated from tea leaves by filtration. B Because the composition of the solution is uniform throughout, it is a homogeneous mixture.

Explanation: While the tea is certainly in the same phase (hence homogeneous ), we certainly could separate the sugar from the water by non-chemical means, i.e. by distillation, or evaporation. And thus we classify it as a mixture….
