Proton acceptors, also known as Brønsted-Lowry bases, are substances that can accept protons (H⁺ ions) during a chemical reaction. They play a crucial role in acid-base chemistry, where they interact with proton donors, or acids, to form new compounds. This process is essential in various biological and chemical systems. In addition to their role in acid-base reactions, proton acceptors can also influence the pH of a solution. When a proton acceptor is added to a solution, it can reduce the concentration of free protons, thereby increasing the pH and making the solution more basic. This property is important in many industrial and environmental applications.
