Element, Compounds, Mixtures

A solvent is a substance that dissolves a solute, resulting in a solution. In the case of Kool-Aid, water is the solvent.

A compound is a substance formed when two or more elements are chemically bonded together. For example, KCl2 is a compound.

Concentration refers to the amount of solute that is dissolved in a given amount of solvent.

To be soluble means that a substance can be dissolved in a solvent.

An unsaturated solution is one that contains less than the maximum amount of solute that can be dissolved in a solvent.

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

An element is a pure substance that cannot be broken down into simpler substances by chemical means. Examples include hydrogen, oxygen, and carbon.

A saturated solution is one in which the maximum amount of solute has been dissolved in the solvent, and any additional solute will remain undissolved.

A supersaturated solution is one that contains more solute than can normally be dissolved at a given temperature, often achieved by heating the solution.

A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.
