2. Biological Buffer: An enzyme-catalyzed reaction was carried out in a 5.7 M intercellular fluid buffer, set at pH 6.8. As a result of the reaction, 0.02 M of diprotic acid was produced. pKa of the buffer is 7.1. A) Write the conjugate-acid and conjugate-base of the intercellular fluid buffer and label each B) What is the pH at the end of the reaction? C) What is the pOH in the absence of a buffer?
