You are given four chemical reactions that are in equilibrium. One of them represents a buffer system—a system that helps resist changes in pH. Part 1:Which reaction shows a buffer system?(Think about which one includes a weak acid and its conjugate base.) Part 2:If a base (like OH⁻) is added to the buffer system you identified, what will happen?(Explain how the buffer reacts to reduce the change in pH.)
