Q: Which type of titration would you use to determine the concentration of a weak acid?

Solution: To determine the concentration of a weak acid, a weak acid-strong base titration is typically used, as it provides a clear endpoint.

Steps: 7

Step 1: Understand what titration is. Titration is a method used to find out how much of a substance (like an acid or a base) is in a solution.
Step 2: Identify the type of acid. A weak acid does not completely dissociate in water, meaning it doesn't break down into ions completely.
Step 3: Choose the right base. For a weak acid, you should use a strong base (like sodium hydroxide) because it will react completely with the weak acid.
Step 4: Set up the titration. You will slowly add the strong base to the weak acid solution while mixing.
Step 5: Use an indicator. An indicator is a substance that changes color at a certain pH level, helping you see when the reaction is complete.
Step 6: Find the endpoint. The endpoint is the point at which the weak acid has reacted completely with the strong base, indicated by a color change.
Step 7: Calculate the concentration. Use the volume of the strong base added and its concentration to calculate the concentration of the weak acid.
