The question below pertains to a titration where 0.30 M HNO 3 (in a buret) is added to 60.0mL of 0.40 M trimethylamine, (CH 3)3N (in the flask).
How is the solution in the flask best characterized after 50. mL of the HNO 3 solution has been added? This is before equivalence point of the titration.
(a) the solution is now a weak base
(b) the solution is now a weak acid
(c) the solution is now a strong base
(d) the solution is now a strong acid
(e) it is now a neutral solution
(f) it is now a buffer solution
