| indicator | a substance that is one color in an acid solution and another color in a basic solution |
| hydronium ion | the result of a hydrogen ion, H+, donated by the acid combining with water |
| Bronsted acid | a substance that donates an H+ ion (proton) to another substance |
| Bronsted base | a substance that accepts an H+ ion (proton) from another substance |
| strong acid | acid that has a high concentration of hydronium ions |
| weak acid | acid that has low concentration of hydronium ions |
| conjugate acid-base pair | two substances that are related to each other by the donating and accepting of a single proton |
| polyprotic acids | acids that can donate more than one proton |
| equivalence point | point in titration where the amounts of titrant and material being titrated are equivalent chemically |
| titration | process to determine equivalent amounts of reactants in a solution |
| logarithm | power of a number to which ten must be raised to equal that number |
| pH | log of the hydronium ion concentration |
| buffer | solution that resists changes in pH even when acids or bases are added |
