Read each question carefully and answer to the best of your ability. Show all work for calculation problems. Use appropriate units and significant figures.
1. What is the primary purpose of an acid-base titration?
To determine the concentration of an unknown solution.
To measure the pH of a solution.
To synthesize a new acid or base.
To create a buffer solution.
2. At the equivalence point of a strong acid-strong base titration, the pH is typically:
Less than 7
Equal to 7
Greater than 7
Dependent on the indicator used
3. A solution of known concentration used in a titration is called the .
4. The point at which the indicator changes color during a titration is known as the .
5. The reaction between an acid and a base is called a reaction.
6. Explain the difference between the equivalence point and the endpoint in an acid-base titration.
7. A weak acid titrated with a strong base will have an equivalence point pH greater than 7.
True
False
8. Phenolphthalein is a common indicator that is colorless in acidic solutions and pink in basic solutions.
True
False
9. A 25.00 mL sample of an unknown concentration of HCl is titrated with 0.150 M NaOH. If 32.45 mL of NaOH is required to reach the equivalence point, what is the concentration of the HCl solution?
