A student prepares a buffer solution by dissolving CH3CH2COOH and CH3CH2COO−K+ in pure water. Write the chemical equations that illustrate how the components of the buffer are able to prevent a drastic change in the pH of the solution when the student adds:
(i) a small amount of H+ into the solution.
(ii) a small amount of HO− into the solution.
