A substance that minimizes changes in pH when acids or bases are added to a solution is called a ______.
Understand the Problem
The question asks for the term that describes a substance which minimizes pH changes in a solution upon the addition of acids or bases. This is a straightforward definition-based question.
Answer
Buffer
A substance that minimizes changes in pH when acids or bases are added to a solution is called a buffer.
Answer for screen readers
A substance that minimizes changes in pH when acids or bases are added to a solution is called a buffer.
More Information
Buffers are crucial in many chemical and biological systems to maintain stable pH levels. They typically consist of a weak acid and its conjugate base, or a weak base and its conjugate acid.
Tips
A common mistake is confusing a buffer with a neutral solution. While buffers can be at a neutral pH, their primary function is to resist changes in pH, not necessarily to be neutral.
