What is the role of a buffer in a titration involving a weak acid and a strong base?

Step 1: Understand that a titration is a method used to determine the concentration of a solution.
Step 2: Recognize that a weak acid does not fully dissociate in water, meaning it does not release all its hydrogen ions (H+).
Step 3: Know that a strong base fully dissociates in water, releasing all its hydroxide ions (OH-).
Step 4: Realize that when you mix a weak acid with a strong base, the pH of the solution can change quickly.
Step 5: Learn that a buffer is a solution that can resist changes in pH when small amounts of acid or base are added.
Step 6: Understand that during the titration, the buffer helps keep the pH stable, allowing for more accurate measurements.
Step 7: Conclude that maintaining a constant pH is important for determining the endpoint of the titration correctly.
