Read each question carefully and answer to the best of your ability. Show all work for calculations.
1. Which of the following describes the equivalence point in an acid-base 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 exactly 7.0.
The point where the concentration of H+ ions equals the concentration of OH- ions.
2. Which piece of laboratory equipment is primarily used to deliver a precise, variable volume of titrant?
Volumetric flask
Pipette
Burette
Beaker
3. A solution of known concentration used in a titration is called the .
4. The point at which an indicator changes color during a titration is known as the .
5. The reaction between an acid and a base is called a reaction.
6. Describe the purpose of an indicator in an acid-base titration.
7. Explain why it is important to rinse the burette with the titrant solution before filling it for a titration.
8. A 25.00 mL sample of an unknown concentration of HCl is titrated with 0.150 M NaOH. If 32.50 mL of NaOH is required to reach the equivalence point, what is the concentration of the HCl solution? Show all your work.
