key term - Brønsted-Lowry Base

Definition

A Brønsted-Lowry base is defined as a substance that can accept protons (H⁺ ions) during a chemical reaction. This definition emphasizes the role of bases not only as neutralizing agents but also in their ability to interact with acids by facilitating the transfer of protons, which is crucial for understanding acid-base behavior in various chemical contexts.
