Read each question carefully and provide detailed answers or calculations as required. Show all your work for numerical problems.
1. Define titration and explain its primary purpose in analytical chemistry.
2. Which of the following indicators would be most suitable for the titration of a strong acid with a strong base?
Methyl orange (pH range 3.1-4.4)
Phenolphthalein (pH range 8.2-10.0)
Bromothymol blue (pH range 6.0-7.6)
Any of the above can be used.
3. The point at which the indicator changes color during a titration is called the .
4. At the equivalence point of an acid-base titration, the moles of acid are to the moles of base.
5. A 25.0 mL sample of an unknown concentration of HCl is titrated with 0.150 M NaOH. If 32.5 mL of NaOH is required to reach the equivalence point, what is the concentration of the HCl solution?
6. A primary standard is a substance of high purity and known concentration used to standardize a titrant.
True
False
7. Consider the titration of 50.0 mL of 0.100 M H₂SO₄ with 0.200 M KOH. Calculate the volume of KOH required to reach the equivalence point.
8. The image above shows a laboratory setup. While it's labeled as chromatography, identify at least two pieces of equipment commonly used in a titration experiment that are also present or similar in this diagram, and briefly explain their function in titration.
