Which of the following statements is true regarding a buffer solution? (2020)

Step 1: Understand what a buffer solution is. A buffer solution is a special type of solution that helps keep the pH level stable.
Step 2: Learn that pH is a measure of how acidic or basic a solution is. A lower pH means more acidic, and a higher pH means more basic.
Step 3: Know that when you add a small amount of acid (which lowers pH) or base (which raises pH) to a buffer solution, it doesn't change the pH much.
Step 4: Realize that this ability to resist changes in pH is what makes buffer solutions important in many chemical and biological processes.
