Answer: There are several ways to make buffer solution in the lab: 1. Using a conjugate acid-base pair with a pKa the same as the desired pH. 2. Using a conjugate acid-base pair with a pKa close to the desired pH and adding a strong acid or base to get the exact pH required 3. Using a weak acid and partially titrate with a strong base or using a weak base and partial titration with a strong acid.
