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

Acid

reactions they undergo

Corrosive

To wear away other materials
