| A | B |
| Bronsted-Lowry acid | any substance that can donate a hydrogen ion (proton) |
| Bronsted-Lowry base | any substance that can accept a hydrogen ion (proton) |
| Amphoteric | capable of functioning either as an acid or as a base |
| Neutralization reaction | when a strong acid and a strong base solution are mixed |
| Conjugate acid | acid formed when a Bronsted-Lowry Base gains a proton |
| Conjugate base | base formed when a Bronsted-Lowry Acid loses a proton |
| Strong acid | an acid that is completely or nearly 100% ionized in solutions |
| Strong base | a base that is completly ionized in solution |
| Weak acid | an acid that does not completly ionise fully |
| Weak base | a base that is only partily ionised in solution |
| Self-ionization of water | when water (2H2O) is dissociated into H3O+ and OH- ions |
| Buffer | solution in which adding small amounts of acid or base does not change the pH |
| Buffer capacity | amount of acid or base that a buffer can neutralization |
| Titration | a carefully controlled neutralization reaction |
