A buffer is prepared using the propionic acidpropionate, Ask an Expert

Academics

A buffer is prepared using the propionic acid/propionate acid-base pair for which the ratio (of acid to base) is 4.50.

(a) Enough strong base is added to convert 27% of HC3H5O2 to C3H5O2-. What is the pH of the resulting solution?

(b) Strong base is added to increase the pH. What must the acid/base ratio be so that the pH increases by exactly one unit from a pH of 4.20?
