Explain how to differentiate between acids and bases using their chemical formulas. How does measuring the concentration of H3O+ allow you to calculate the pH of a solution, and how can you use pH to determine if a solution is acidic or basic? What’s the difference between a strong and weak acid (or a strong and weak base)? Describe the components of a buffer. How can a buffer neutralize both added acid and added base? Explain what happens in a buffer solution when a strong acid is added: what reaction occurs to keep the pH relatively constant? Finally, describe how you could make a buffer if you only have weak acid available, but you also have access to both a strong acid and a strong base.
