| acid | a substance that is capable of releasing hydrogen ions (H+) and producing hydronium ions in water solutions (H3O+) |
| base | a substance that produces hydroxide ions, (OH-) in water. |
| aqueous | consisting mostly of water |
| pH | a number that shows acidity; it is a measure of hydronium ion (H3O+) concentration of a solution. |
| neutralization | chemical reaction in which equal numbers of hydronium ions (from the acid) and hydroxide ions from the base) combine to form water and a salt. |
| salt | a compound containing a positive ion from a base and a negative ion from an acid. |
| dissociation | Breaking down of a compound into its components. |
| ionizes | When a substance breaks into its ionic components. |
| conjugate base | A substance which can gain a H+ ion to form an acid. |
| conjugate acid | A substance which can lose a H+ ion to form a base. |
