Question 7 (15 pts) For a solution made by dissolving 0.7340 g of fluoroacetic acid (MM = 78.04 g/mol, pKa = 2.590) in 750.0 mL of pure water, what is the pH error (difference) between the approximate and rigorous (quadratic) calculated answers? (i.e. calculate Error = pH(approximate) – pH(quadratic)) Question 8 (25 pts) For the titration of 50.00 mL of a 0.2000 M solution of anilinium ion (Ka = 2.510 x 10-5 M) with 0.2000 M NaOH calculate the VEP and the pH at each of the titration volumes indicated. Calculate VEP Before the titration starts (0.00 mL of titrant added) At a volume that is 5.00 mL before the equivalence point At the equivalence point of the titration At a volume that is 2.00 mL after the equivalence point Question 9 (20 pts) Calculate the pH of a buffer solution that results when 50.0 mL of 0.1250 M NH3 is mixed with 20.0 mL of a 0.200 M NH4Cl solution.
