A 25.00 mL sample containing a certain monoprotic weak acid, HA
(Ka 4.5 x 10-5) requires 16.25 mL of 0.102 M
NaOH to reach the endpoint of titration.
a) Determine the concentration of the acid in the sample.
b) Determine the pH of the original solution before any titrant
was added.
c) Determine the concentration of the conjugate base
A- at the endpoint of titration.
d) Determine the pH of the solution at the endpoint of the
titration.
