17) A 900.0 mL sample of 0.18 M HCIO4 is titrated with 0.27 M NaOH. Determine the pH of the solution after the addition of 270.0 mL of NaOH. + 19) What is the solution pH when 0.10 mol of his added to a 2.0-liter buffered solution created from 0.31 M NH3 (Kb = 1.8 x 10-5) and 0.26 M NH4F. = 20 A 1.00 L buffer solution is 0.150 M in HC7H502 and 0.250 M in LiC7H502. Calculate the pH of the solution after the addition of 100.0 mL of 1.00 M HCI. The Ka for HC7H502 is 6.5 x 10-5. 22) What is the pH of a solution prepared by mixing 50.00 mL of 0.10 M methylamine, CH3NH2, with 20.00 mL of 0.10 M methylammonium chloride, CH3NH3Cl? Assume that the volume of the solutions are additive and that Kh = 3.70 x 10-4 for methylamine.
