Cаlculаte the fоllоwing аnswers using scratch paper and submit tо the 'Exam 3 Scratch Upload' assignment. 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. (Kb of NH3 is 1.80 x 10-5 M) Question 10 (10 pts) Given the following information for nitrous acid, calculate CT, pH and [HA].Make sure your calculations are clear and the answers easily identifiable. Ka (nitrous acid) = 7.21 x 10-4 M; [A-] = 0.105 M; α0 = 0.413; α1 = 0.587 Add each of the answers (numeric value plus unit) below. Q7: Q8a:Q8b:Q8c:Q8d:Q8e: Q9: Q10:
