Question

Quizplus · Accepted Answer

Amphoteric molecules are able to act as both an acid or base depending on the pH of their environment. This is because they have both acidic and basic groups within their structure that can donate or accept protons as needed. Examples of amphoteric molecules include water and amino acids. The other choices are not related to the concept of reversible acid-base behavior.
