Aqueous Solution

A solution in which the solvent is water, and the solute can be a liquid or a solid.

Concentration

The amount of solute present in a given quantity of solvent or solution. It can also be defined as the number of moles per unit volume (M/V)

Standard Solution

A solution whose concentration is already known.

Analyte Solution
