Read each question carefully and provide your best answer. Refer to your knowledge of titration curves and acid-base chemistry.
1. Which of the following best describes the equivalence point in a titration?
The point where the indicator changes color.
The point where the moles of acid equal the moles of base.
The point where the pH is 7.0.
The point where the solution becomes a buffer.
2. What type of titration curve is characterized by a long, steep pH jump around the equivalence point, typically between pH 3 and 11?
Strong acid-strong base titration
Strong acid-weak base titration
Weak acid-strong base titration
Weak acid-weak base titration
3. The region on a titration curve where the pH changes very little upon addition of small amounts of acid or base is known as the region.
4. For a weak acid-strong base titration, the pH at the equivalence point will be than 7.
5. The point at which the indicator changes color during a titration is called the .
6. Describe the key differences in the shapes of titration curves for a strong acid-strong base titration versus a weak acid-strong base titration. Focus on the initial pH, the pH at the equivalence point, and the buffer region.
7. Refer to the titration curve shown. Is this likely a strong acid-strong base, strong acid-weak base, or weak acid-strong base titration? Justify your answer based on the curve's characteristics.
8. In a strong acid-weak base titration, the pH at the equivalence point will be less than 7.
