A mixture is formed when two or more substances are physically mixed together. A compound is formed when two or more substances are chemically combined through a chemical reaction. The components of a mixture can be separated with relative ease, whereas the components of a compound are almost impossible to separate without a chemical reaction.Know More
A mixture involves the physical combination of substances. The substances can be combined in any ratio to form the mixture, and the individual substances retain their chemical properties.
A compound requires a chemical reaction between two or more substances and the compound formed has different chemical properties compared to the individual substances that were initially combined. Unlike mixtures, compounds can only be formed if the substances are combined in certain fixed ratios.
Mixtures are easy to separate to their individual components through physical means such as evaporation, filtration, distillation, precipitation and chromatography. Compounds cannot be broken down to their individual elements through physical means. For example, to form a mixture of iron filings and sulfur powder, any ratio of iron to sulfur can be used to mix the components. However, to form a compound, seven parts of iron filings have to be heated with four parts of sulfur powder to form a compound called iron sulphide. To separate the iron from sulfur in a mixture, a magnet can be used to attract all the iron filings, leaving only the sulfur behind. The compound iron sulphide cannot be separated using any physical means.Learn more in Solutions & Mixtures
Steel is a mixture. It is a mixture because it contains atoms and molecules of varying types, making intermolecular bonds that are not as strong as those found in compounds.Full Answer >
Heterogeneous mixture is a term used in chemistry to describe a mixture of substances that are not uniformly distributed. In a heterogeneous mixture, the various components can be easily picked out from one another.Full Answer >
In scientific language, a solution is a mixture of at least two substances in which the particles of the substances are of atomic or molecular size. A solution is a homogeneous mixture, which means that all parts of the mixture are exactly the same as every other part.Full Answer >
