A buffer is prepared using the butyric acid/butyrate acid-base pair. The ratio of acid to base is 2.2 and Ka for butyric acid is

(a) What is the pH of this buffer?

(b) Enough strong base is added to convert 15% of butyric acid to the butyrate ion. What is the pH of the resulting solution?

(c) Strong acid is added to the buffer to increase its pH. What must the acid/base ratio be so that the pH increases by exactly one unit (e.g., from 2 to 3) from the answer in (a)?
