Due On Tue, Apr 26 at 9:00 pm (in 11 hours) Your boss has asked you to prepare a solution of an acetate buffer. Unfortunately, you only have a bottle of 0.460 M of acetic acid, CH3COOH, and a bottle of 0.200 M of NaOH. Note that the pK, of CH3COOH is 4.74. Total Marks 100 a) How many moles of CH3COOH are in 100.0 mL of a 0.460 M solution of acetic acid? Grade 0 CH3COOH : mol Task Navigation b) How many moles of NaOH must you add to the 100.0 mL 0.460 M acetic acid to obtain a buffer solution with a pH of 4.50 ? 4 NaOH : mol 5 6 7 8 c) What volume of 0.200 M NaOH must you add, in mL, to reach that pH ?
