Questions & Step-by-Step Solutions
Which of the following is a characteristic of a buffer solution?
Correct Answer: A buffer solution resists changes in pH.
Step 1: Understand what a buffer solution is. A buffer solution is a special type of solution that helps maintain a stable pH level.
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 a small amount of 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 the key characteristic of a buffer solution.
