Question 17.14: Calculating the pH at the Equivalence Point in the Titration...

Calculating the pH at the Equivalence Point in the Titration of a Weak Acid by a Strong Base

Calculate the \mathrm{pH} of the solution at the equivalence point when 25 \mathrm{~mL} of 0.10  \mathrm{M} nicotinic acid is titrated by 0.10  \mathrm{M} sodium hydroxide. K_{a} for nicotinic acid equals 1.4 \times 10^{-5}.


At the equivalence point, equal molar amounts of nicotinic acid and sodium hydroxide react to give a solution of sodium nicotinate. You first calculate the con- centration of nicotinate ion (stoichiometry problem). Then you find the \mathrm{pH} of this solution (hydrolysis problem).
