| A | B |
| neutralization | acids react with bases to form water and a salt |
| salt | ionic substance composed of a positively charged metallic or polyatomic ion and a negative ion other than the hydroxide ion |
| Arrhenius acid | a substance whose water solution contains the hydrogen ion as the only positive ion |
| hydronium ion | one water molecule plus one hydrogen ion |
| Arrhenius base | a substance whose water solution contains the hydroxide ion as the only negative ion |
| binary acids | composition of hydrogen and one other element |
| titration | adding measured volumes of an acid/base of known concentration to an acid/base of unknown concentration until neutralization occurs |
| pH scale | expresses the amount hydrogen ions as a number from 0 to 14 |
| indicator | a substance that changes color when it gains or loses a proton |
