| Question | Answer |
| What is bronsted-lowry acid? | a proton donor |
| what is a bronsted-lowry base? | a proton acceptor |
| explain what happens to a buffer when an acid is added to it | 1. H+ ions react with the A- to produce more HA. 2. The [A-] and [HA] are very large so an increase in [HA] doesn't affect the pH of the solution |
| explain what happens to a buffer when a base is added to it. | 1. OH- reacts with H+ ions to produce water. 2. The position of equilibrium is then shifted to the right to produce more H+ ions. |
| what is the function of the weak acid component in a buffer solution? | to act as a source of HA which can remove any added OH- |
| what is the function of the salt component of a buffer? | to provide A- ions that can react with H+ ions to produce HA. |
