To the nearest hundredths, what is the pH at the end of an enzyme-catalyzed reaction if it were carried out in a 0.1 M buffer initially at pH 2.01, and 0.005 M 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 2.01, 6.7, and 11.38.) (The enzyme's normal environment is the stomach.) This is all the information given

Does anyone know how to do this? Thanks in advance!
Enzyme Activity (ml) Effect of pH on (amylase) enzyme activity. For determination of optimum assay pH of the enzyme reaction, 0.05 M Na2HPO4-NaH2PO4 buffer was used. The reaction was carried out for 10 min at 50°C in a shaking water. The enzyme activity was measured and the results are presented on graph, Bars represent means standard deviations for three replicates. 1. What do the error bars in this graph represent?...
