A) When a 25.1 mL sample of a
0.434 M aqueous acetic acid
solution is titrated with a 0.320 M aqueous
sodium hydroxide solution, what is the pH after
51.1 mL of sodium hydroxide have
been added?
pH =
B) When a 17.5 mL sample of a
0.492 M aqueous nitrous acid
solution is titrated with a 0.451 M aqueous
potassium hydroxide solution, what is the pH at
the midpoint in the titration?
pH =
