1. Measuring the pH of a Butanoic Acid Solution:
- Prepare a solution of butanoic acid in water.
- Use a pH meter or pH test strips to measure the pH of the solution.
- If the pH is less than 7, it indicates that the acid is donating H+ ions to the water, making the solution acidic.
2. Conductivity Measurements:
- Prepare a solution of butanoic acid in water.
- Use a conductivity meter to measure the electrical conductivity of the solution.
- A weak acid will have a lower conductivity compared to a strong acid at the same concentration. This is because weak acids do not completely dissociate, resulting in fewer ions in the solution.
