Buffer Preparation: There are several ways to prepare a buffer solution ofa specific pH. One method is mentioned in the manual. The other way is mentioned below but not in a correct order. Once the pH is adjusted to the desired pH, dilute the solution to the final desired volume. 1. Measure the pH of the solution using a pH meter. 2. 3. Adjust the plH to the desired value using a strong base or acil like NaOH or HCl. 4. Prepare a solution with an acid and its conjugate base by dissolving them in about so% of the volume of water required to obtain the final solution volume. What is the correcet order of preparing the buffer solution: 04.2.3.1 O1,3-4,1 04,1,2,1 Oa,3,14

In a buffer solution which of the following statements are true. (circle all that apply a.[base] > [acid], pH > pKa b.[base] < [acid], pH > pKa c.[base] < [acid], pH < pKa d.[base] > [acid], pH < pKa
Why is it important not to add too much HCl and go past the endpoint? O The volumne of acid added will be lower than expected for the calculations. O The color change can reverse. O The solution could bubble out of the flask. O The volume of acid added will reflect more than acid required to neutralize the base.
