| Question | Answer |
| What is the equilibrium in an acid buffer? | HA(aq) = H+(aq) + A-(aq) |
| 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 |
| What is a basic buffer? | a mixture of a weak base and a salt of that base |
| Give an example of what a buffer might be used for | detergents or shampoos |
| What equation is used to calculate the pH of a buffer? | Same calculation used for a weak acid Ka |
