A buffer was prepared from a concentrated propanoic acid (10.0 M) solution in two steps. First, 10.0 mL of the concentrated acid solution was diluted by adding 390 mL of distilled water. a) Calculate the concentration of the diluted propanoic acid solution. b) Next, 160 mL of 0.200 M NaOH was added to the diluted propanoic acid solution. i) Write down an equation representing the reaction between propanoic acid and NaOH. ii) By constructing an ICE table, calculate the pH of this buffer solution. The pKa of propanoic acid is 4.87 You should show all working in your answer. c) In a further investigation, a student prepared a pH 5.0 buffer solution by mixing propanoic acid and sodium propanoate. In the prepared buffer, the concentration of propanoic acid was 0.200 M. Determine the concentration of the sodium propanoate.
