Question

A weak acid is titrated with 0.1236 M NaOH. From the titration curve you determine that the equivalence point occurs after exactly 12.42 mL of NaOH have been added. What is the volume of NaOH at the half-equivalence point (a.k.a. the midpoint)

Answer:The volume of NaOH required at the half-equivalence point is 6.21 mLExplanation:The chemical equation for the reaction of a weak acid with NaOH follows:From the equation, we can say that NaOH and weak acid is present in a 1 : 1 ratio.

We are given:Volume of NaOH required at equivalence point = 12.42 mL

The volume of NaOH required at half-equivalence point will be =

Hence, the volume of NaOH required at the half-equivalence point is 6.21 mL
