Question:

Consider the titration of 100.0 mL of 0.40 M HBr with 0.60 M KOH. Calculate the pH after 30.0 mL of KOH has been added.

Titration:

The titration involving a strong acid and strong base analyte is much easier than when the procedure involves a weak acid and a weak base analyte because, in the former, there is no need to consider the pKa or pKb to determine the appropriate indicator to use because, almost always, the indicator used is phenolphthalein.
