Final answer:
Acids donate protons while bases accept protons in Brønsted-Lowry theory of acids and bases.
Explanation:
According to the Brønsted-Lowry theory, an acid is a `proton donor`, which means it gives away protons (H+). This role of an acid is crucial in acid-base reactions.
In contrast, a base is a `proton acceptor`, taking up protons in the reaction. Understanding these roles is essential in comprehending acid-base chemistry.
In a chemical reaction, an acid donates a proton to a base, leading to the formation of conjugate acids and bases.
