Hi, help me with this question, please.
Explain how a solution containing propanoic acid and sodium propanoate can function as a buffer solution. Your answer must include balanced chemical equations, physical states included.
C3H5O2H C3H5O2- + H+
When a strong acid is added to the system, it shifts the equilibrium towards the initial substances, and the addition of a strong base binds protons and shifts the equilibrium towards the products, while, as a result, the pH of the solution changes slightly.
