What is the role of a buffer solution in a titration?
Correct Answer: A buffer solution helps maintain a constant pH during a titration.
- Step 1: Understand what a titration is. It is a method used to determine the concentration of a solution by adding a solution of known concentration.
- Step 2: Know what a buffer solution is. It is a special solution that can resist changes in pH when small amounts of acid or base are added.
- Step 3: Recognize the importance of pH in titrations. The pH level can affect the reaction and the results.
- Step 4: Learn that during a titration, especially with weak acids and strong bases, the pH can change quickly.
- Step 5: Understand that a buffer solution helps keep the pH stable, allowing for more accurate measurements.
- Step 6: Conclude that using a buffer solution in a titration is important for getting reliable results.
