| Acid | a compound that dissociates in solution to form hydrogen ions |
| Base | a compound that dissociates in water to form hydroxide ions |
| Salt | a compound made up of any positive ion except hydrogen and any negative ion except hydroxide |
| Indicator | a substance that shows the presence of another form of matter by a color change |
| Litmus | an indicator for acids and bases |
| Radical | a group of atoms that acts like a single atom |
| Phenolphthalein (PHTH) | an indicator that is colorless in acid and pink in base |
| Neutralization reaction | the process by which acids and bases cancel each other out and produce salts and water |
| Hydrogen ion (H+) | A hydrogen atom that has lost its only valence electron; therefore, it is a single proton |
| Hydroxide ion (OH-) | a radical containing a hydroxyl group |
| Dissociate | to seperate |
| strength of an acid or a base | the degree to which acids and bases dissociate in water to produce ions |
| pH scale | the scale of numbers between 1 and 14 that is used to express the degree to which a compound in sloution with water acts as an acid or as a base |
