Solution: Predict whether the equivalence point of each of the following titrations is below, above, or at pH=7.KOH titrated with HBr

Problem

Predict whether the equivalence point of each of the following titrations is below, above, or at pH=7.

KOH titrated with HBr

Solution

Hey there! We’re being asked to predict whether the equivalence point of the titration of KOH with HBr is below, above or at pH=7.

Recall that at the equivalence point of a titration:


moles acid = moles base


Recall that in the titration of a strong acid and strong base, the equivalence point occurs at pH 7If there is an equal amount of moles for both the strong acid and strong base then the pH of the solution will be 7
