A solution is best described as?

A solution is best described as a homogeneous mixture. This means that the components of a solution are evenly distributed throughout, resulting in a mixture that appears uniform at a molecular level. In a solution, one substance (usually the solvent) dissolves another substance (the solute), leading to a single phase where the properties are consistent throughout.

For instance, when table salt is dissolved in water, it forms a saltwater solution where the salt (solute) is uniformly distributed within the water (solvent), creating a solution that does not separate into distinct layers or regions. This characteristic distinguishes solutions from heterogeneous mixtures, where the different components can be seen and may not be uniformly distributed. A pure substance, on the other hand, consists of only one type of particle and does not have the mixture of different substances, while a compound specifically refers to a substance formed when two or more elements are chemically bonded.
