Solution
A uniform mixture that contains a solvent and at least one solute
Solvent
Part of a solution present in the largest amount
Solute
The substance that is present in a solution in a smaller amount and is
dissolved by the solvent
Dilute solution
Has only a little solute dissolved in an amount of solvent
Concentrated solution
Has a lot of solute dissolved in an amount of solvent
Saturated solution
When the solution cannot dissolve any more solute
