| A | B |
|---|
| acid | produces hydrogen ions when dissolved in water |
| base | a compound that produces hydroxide ions when dissolved in water |
| OH- | hydroxide ion |
| H+ | hydrogen ion, used the same way as H3O+ |
| self-ionization | the reaction in which two water molecules react to give ions (H+ and OH-) |
| acidic solution | one where the H+ concentration is greater than the OH- concentration |
| basic solution | one where the H+ concentration is less than the OH- concentration |
| pH of a solution | the negative log of the [H+] |
| pOH of a solution | the negative log of the [OH-] |
| Arrhenius acid | compound containing hydrogen that can ionize to produce H+ |
| Arrhenius base | compound containing hydroxide that can ionize to produce OH- |
| dissociated | ionized: taken apart |
| concentrated | large number of acid or base moles in solution: high M |
| dilute | small number of acid or base moles in solution: low M |
| strong acid or base | one that dissociates (ionizes) completely in solution |
| weak acid or base | one that only dissociates (ionizes) a small amount in solution |
| indicator | a weak acid or base that will ionize at a certain pH range producing color changes |
