Brønsted-Lowry theory of acids and bases

The Brønsted-Lowry theory defines acids as substances that donate protons (H⁺ ions) and bases as substances that accept protons. According to this theory, when an acid reacts with a base, the acid donates a proton to the base. This interaction helps explain a wide range of chemical reactions, including those in biological systems. For example, in our bodies, various acids and bases interact to maintain pH levels, which are crucial for proper physiological function. This broader definition allows for more complex acid-base behavior beyond just traditional definitions involving taste or reactivity.
