Questions & Step-by-Step Solutions
What is the significance of using a buffer solution in a titration involving weak acids?
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 weak acid is. A weak acid does not completely dissociate in water, meaning it does not release all its hydrogen ions.
Step 3: Learn about pH. pH is a measure of how acidic or basic a solution is.
Step 4: Recognize that during a titration, the pH of the solution can change quickly, especially when adding a strong base to a weak acid.
Step 5: Understand what a buffer solution is. A buffer solution is a mixture that can resist changes in pH when small amounts of acid or base are added.
Step 6: Realize that using a buffer solution in a titration helps keep the pH stable, which is important for accurate measurements.
Step 7: Conclude that a stable pH allows for better observation of the endpoint of the titration, leading to more precise results.
