| Amphoteric | A substance that can act as an acid or base in a reaction |
| Arrhenius acid | A substance that yields hydrogen (H+) ions as the only positive ions in aqueous solution |
| Arrhenius base | A substance that yields only hydroxide (OH-) ions as the only negative ions in aqueous solution. |
| Bronsted-Lowry Acid | Any species (molecule or ion) that can DONATE a proton (H+) to another species |
| Bronsted-Lowry base | Any species (molecule or ion) that can combine with (ACCEPT) a proton |
| electrolyte | A substance that dissociates fully or partially into ions when dissolved in solvent, producing a solution that conducts electricity |
| hydronium ion | A water molecule with a positive charge due to the presence of an additional hydrogen ion. Usually found in acids. |
| hydroxide ion | The diatomic ion (OH-); also called a hydroxyl group. Usually found in bases |
| indicator (acid/base) | A substance that undergoes a sharp, easily observable change when conditions in its solutions change. (Acid=red, Base=blue) |
| neutralization | The reaction that occurs when equivalent quantities of an acid and a base are mixed, producing a salt and water. |
| pH scale | Ranges from 1 to 14. A pH of 7 indicates a neutral solution. Less than 7 = acid. Greater than 7 = base. |
| titration | A procedure involving the addition of a measured addition of a measured quantity of a standard acid or base solution to an unknown base or acid solution to determine the amount of the unknown solution. |
