ACETIC ACIDA Complete the following exercises in the space below (28 pts) (a) Write the net ionic equation (3 pts) (b) Sketch the titration and derivative in the plot below. Include and clearly label: all equivalence point volume(s), the pH at each equivalence point, and the point(s) where pH = pka. (15 pts) (c) Determine the Ka. (2 pts) (d) Calculate the expected pH at the equivalence point and compare it with the experimental value. (4 pts) This is the same as in the prelab, see Eqns. 12 and 13 (e) Identify the buffer region (pK, 1) and identify the buffer species. (2 pts) (f) State whether either of the following would function as an appropriate indicator (2 pts). Phenolphthalein (pH range 8.0 - 9.8), Bromocresol green (pH range 3.8-5.4)
