How does the pH at the equivalence point differ between the titration of a strong acid with a strong base and a weak acid with a strong base?

• A. The equivalence point pH is unpredictable and varies randomly.
• B. The equivalence point pH is lower for weak acids compared to strong acids.
• C. The equivalence point pH is always 7 regardless of the acid or base strength.
• D. The equivalence point pH is 7 for strong acids and bases, but higher for weak acids.

Answer: (D)
