Determine the pH at the equivalence point in the titration of 41.0 mL 0.096 M formic acid with 0.108 M NaOH at 25oC.

Question

Calculate the pH of a solution that is 0.22 M pyridinium ion (C5H5NH+) at 25oC.

Answer 1

What is it that you don't understand about the problem? The pH at the equivalence point of formic acid and NaOH is determined by the hydrolysis of the salt, i.e., sodium formate.
