 acidic solution | a solution whose pH is less than 7 |
| Arrhenius model | An acid is a substance that contains hydrogen and ionizes to produce hydrogen ions in aqueous solution; A base is a substance that contains a hydroxide group and dissociates to produce a hydroxide ion in aqueous solution |
| basic solution | a solution whose pH is greater than 7 |
| Bronsted-Lowry model | a model of acids and bases in which an acid is a hydrogen ion donor and a base is a hydrogen ion acceptor |

| conjugate acid | the particle formed when a base gains a hydrogen ion |
| conjugate base | the particle that remains when an acid has donated a hydrogen ion |
| neutralization reaction | the reaction of an acid and a base to form a neutral solution of water and a salt |
| pH | the negative logarithm of the hydrogen ion concentration of a solution |
| pOH | the negative logarithm of the hydroxide ion concentration of a solution |
| strong acid | an acid that ionizes completely in aqueous solution |
| strong base | A base that dissociates completely into ions in solution. |
