Acids, Bases and Solutions
Science

A compound that changes color when exposed to an acid or a base, like litmus paper
Acid base indicator
A compound that changes color when exposed to an acid or a base, like litmus paper. Acid base indicator. An acid base indicator is a substance that helps identify whether a solution is acidic or basic by changing color.

A solution that contains the maximum amount of dissolved solute at a given temperature
Saturated solution
A solution that contains the maximum amount of dissolved solute at a given temperature. Saturated solution. A saturated solution is one where no more solute can dissolve in the liquid at that specific temperature.

A solution with more dissolved solute at a given temperature, than a saturated solution
Supersaturated solution
A solution with more dissolved solute at a given temperature, than a saturated solution. Supersaturated solution. A supersaturated solution contains more dissolved material than it normally would hold at a given temperature, and is unstable.

A mixture in which the solid particles are large enough to be seen
Suspension
A mixture in which the solid particles are large enough to be seen. Suspension. In science, a suspension is a type of mixture where small solid particles are dispersed throughout a liquid but are not dissolved, allowing them to eventually settle.
