5. Answer the following questions a-d: Type all questions and answers. a. i) Look at your results for Table II. Which one of the three buffers was the best buffer overall? ii) Look at the number of drops. Which solution preparation was the best buffer against HCI? iii) Which was the best buffer against NaOH? b. Looking at the method of preparation and molarities in the prepared solutions; Explain why you think the particular preparation chosen in answer (a) above buffered better against HCl or NaOH. c. Using your text book or internet sources, summarize the use of another chemical buffer in our body, environment, or industrial usage THAT WAS NOT MENTIONED IN THIS EXPERIMENT. Include your reference. Just saying "so and so is a buffer" does not answer this question. Your answer should include appropriate reactions as well. d. Was water a good buffer? Explain your answer. Be careful to not just restate the facts.
