Questions & Step-by-Step Solutions
What is the role of a buffer solution?
Step 1: Understand that pH is a measure of how acidic or basic a solution is.
Step 2: Know that a buffer solution is a special type of solution that helps keep the pH level stable.
Step 3: Learn 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 buffers work by using weak acids and their corresponding bases to neutralize added acids or bases.
Step 5: Remember that this stability is important in many chemical and biological processes.
