| What happens to the acid buffer when you add alkali | OH- reacts with HA to produce water and A-. |
| Which way does the acid buffer equilibrium shift when an alkali is added? | Right |
| Which way will the acid buffer equilibrium shift if an acid is added? | Left |
| What happens when an acid is added to an acid buffer? | H+ combines with A- to produce more HA |
| What is an acid buffer made from? | A mixture of a weak acid and a soluble salt of the same acid |
