<u>Answer:</u> The volume of NaOH required at the half-equivalence point is 6.21 mL
<u>Explanation:</u>
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
