Q: What is the primary role of a buffer solution?
Solution:
A buffer solution maintains a stable pH when small amounts of acid or base are added.
Steps: 5
Show Steps
Step 1: Understand what a buffer solution is. A buffer solution is a special type of liquid that can resist changes in pH.
Step 2: Know what pH means. pH is a measure of how acidic or basic a solution is.
Step 3: Learn that buffers are made of weak acids and their salts or weak bases and their salts.
Step 4: Recognize that when you add a small amount of acid (which lowers pH) or base (which raises pH) to a buffer, it doesn't change the pH much.
Step 5: Conclude that the primary role of a buffer solution is to keep the pH stable, even when small amounts of acids or bases are added.
