proton acceptor

A proton acceptor is a substance that can accept protons (positively charged hydrogen ions) from other molecules during a chemical reaction. This concept is often used in acid-base chemistry: acids donate protons, while bases accept them. When a base accepts a proton, it can change its structure and properties, often affecting how it interacts with other substances. In everyday terms, you can think of a proton acceptor as a sponge that soaks up protons from its surroundings, helping to balance chemical reactions and influence the acidity or alkalinity of a solution.
