An enzyme-catalyzed reaction was carried out in a solution buffered with 0.03 M phosphate, pH 7.2. As a result of the reaction, 0.004 mol/liter of acid was formed. a. What was the pH at the end of the reaction?
b. What would the pH be if no buffer were present?
c. Write the chemical equation showing how the phosphate buffer resisted a large change in pH.
