Molarity

The number of moles of solute in one liter of solution, calculated as moles of solute divided by liters of solution (M = mol/L).

Solution

A homogenous mixture where a solvent dissolves a solute, resulting in a uniform composition.

Solvent

The substance that dissolves a solute to form a solution, can be a liquid, solid, gas, or supercritical fluid.

Unsaturated solution

Can dissolve more solute than it currently contains.

Saturated solution

Contains the maximum amount of solute that can dissolve at a given temperature.

Aqueous solutions

Solutions where water is the solvent, polar and ionic compounds dissolve better than nonpolar compounds.

Percent by mass

The percentage of the solution's weight due to the solute's mass.

Percent by volume

The percentage of the solution's volume due to the solute's volume.

Titration

The process of determining the concentration of a substance by reacting it with a known concentration reagent.

Line Spectra

The specific wavelengths of light emitted or absorbed by an atom due to electron transitions between energy levels.
