Question
For the complete titration of a weak monobasic acid against a strong base, which of the following indicators is most appropriate to accurately detect the equivalence point?
Answer: B
💡 Solution & Explanation
In the titration of a weak acid and a strong base, the equivalence point lies in the basic region (typically pH > 8) due to the anionic hydrolysis of the formed salt. Phenolphthalein has a pH transition range of 8.2 to 10.0, which perfectly encompasses this equivalence point, making it the most suitable indicator.
