Question:
Consider the titration of 100.0 mL of 0.45 M HBr with 0.35 M KOH. Calculate the pH after 90.0 mL of KOH has been added.
Titration:
In the titration of a strong acid or a strong base, the pH that is almost always considered is pH 7 because this is the pH at which the equivalence point will occur. Since phenolphthalein changes color at this pH range, this is the most common indicator for this purpose.
