Expert Solution
Step 1

A buffer system is a solution that can resist changes in pH when small amounts of acid or base are added to it. It consists of a weak acid and its corresponding conjugate base, or a weak base and its corresponding conjugate acid. The buffer system works by reacting with any added acid or base in a way that minimizes the change in pH.
