answer D only Exercise onBuffer solutions1. a) What is meant by the term "buffer solution"?b) Calculate the pH of a buffer solution which contains the weak monoprotic acid,propanoic acid (CH₂CH₂COOH), in concentration 0.1 mol/L and sodium propanoatein concentration 0.05 mol/L. K, of propanoic acid is 1.26 x 10³ mol/L.c) Give equations to show how the above solution fulfills its buffer function.d) Calculate the pH of the solution after 0.01 moles of NaOH are added to 500 mL ofthe solution.e) Calculate the pH of the solution after 0.01 moles of HCI are added to 500 mL ofthe solution.f) Calculate the pH after 0.01 moles of NaOH is added to 500 mL of water.

pH of buffer solution can be calculated using Henderson hasselbalch equation.
