Brønsted acids

A Brønsted acid is a substance that donates a proton (H⁺ ion) to another substance during a chemical reaction. Think of it as a "proton donor." In a solution, when a Brønsted acid interacts with a base, the acid releases its proton, and the base accepts it. This process explains many common reactions, such as vinegar (acetic acid) acting as an acid by donating protons. Understanding Brønsted acids helps us grasp how acids and bases behave in chemistry, biology, and everyday phenomena involving pH and solution reactions.
