Read each question carefully and answer to the best of your ability. Refer to your knowledge of titration curves and acid-base chemistry.
1. What is a titration curve, and what information can be obtained from it?
2. The point at which the moles of acid equal the moles of base in a titration is called the .
3. A is a substance that changes color at a specific pH range, indicating the endpoint of a titration.
4. Which of the following statements is true regarding a strong acid-strong base titration curve?
The equivalence point is at pH 7.
The initial pH is very high.
The curve has a gradual slope throughout.
The pH changes rapidly at the beginning.
5. Consider the titration curve below, which represents the titration of an unknown acid with a strong base.
a) Is the unknown acid strong or weak? Justify your answer based on the curve.
b) Estimate the pH at the equivalence point.
6. For a weak acid-strong base titration, the equivalence point will always be at a pH greater than 7.
True
False
7. Explain why the choice of indicator is crucial for accurate titration results.
