In science, a solution is
defined as a type of homogenous mixture. Examples of solutions include salt water, sugar water,
and Kool Aide.
Mixtures are made up of more two or more
substances. Unlike chemical reactions, no new substances are created when substances are
combined within a mixture. A homogenous mixture is a mixture that has a uniform composition.
This means that the substances within a mixture are uniformly dispersed and cannot be easily
differentiated from one another.
A solute and a solvent are the two parts of
a solution. The solute is dissolved in the solvent. The word dissolve can be traced back to the
Latin word dissolvere, which means to loosen. The solute is thing that is dissolved. The
solvent is the substance that does the dissolving.
When a solute is dissolved
in a solvent, the solute particles become surrounded by solvent particles. The phrase likes
dissolve likes implies that nonpolar substances will dissolve in other nonpolar substances.
Likewise, polar substances will dissolve in other polar substances. When a polar substance is
dissolved in another polar substance,
charges attract one another.
