The Acidic Environment > 3. Acids >
Describe acids and their solutions with the appropriate use of the terms strong, weak, concentrated and dilute
- Strong acid: An acid that completely ionises in water to form hydrogen ions, leaving no neutral acid molecules remaining.
- Weak acid: An acid that only partially ionises in water to from hydrogen ions, leaving neutral molecules remaining.
- Concentrated solution: A solution in which the total concentration of acid is high (a large amount of solute is contained in a small amount of solution).
- Dilute solution: A solution in which the total concentration of acid is low (a small amount of solute is contained in a large amount of solution).
