To the nearest hundredths, what is the pH at the end of an enzyme-catalyzed reaction if it were carried out in a 0.1M buffer initially at pH2.17, and 0.006M of acid (H+)was produced during the reaction? (The buffer used was a polyprotic acid of the general form: H3A; the three pKas of this polyprotic acid are 2.17, 6.69, and 11.31.) (The enzyme's normal environment is the stomach.)
