ACID- BASE CONCEPT. There are 4 types of acid-base concepts: 1. Arrhennius Concept. 2. Lowry-Bronsted Concept. 3. Lewis Concept. 4. Solvent System Concept.

Acids form hydrogen ions H+(H2O)n in aqueous solution. Bases form hydroxide ions in aqueous solution. Examples of Arrhenius acids (in water): HCl, H2SO4, etc.
