12. Why might a chemist add a buffer to a solution? The buffer can keep the pH stable when small amounts of acid or base are added. The buffer reacts with the acid or base in solution to form a useful product. The buffer changes color to indicate the pH of the solution. The buffer can magnify the changes to pH caused by adding small amounts of acid or base.
