21:34 Acid indigestion is a common ailment caused by the overproduction of stomach acid, HCI. Over-the-counter antacids provide some relief from the symptoms of acid indigestion. They are generally made up of some mixture of weak bases such as Mg(OH)2, Al(OH)s, and Cacos that can react with acid as shown in these net ionic equations: H*(aq)+OH"(aq)- H2O(1) 2H"(aq) +CO"(aq) - H2O(1)+CO:(g) In this exercise, the method of titration will be used to determine the number of moles of H+ neutralized per gram of antacid. In the "back-titration," a portion of antacid will be mixed with an excess of HCI. The H* that has not reacted with the antacid is then titrated with standardized NaOH in the presence of the indicator bromophenol blue to a blue end point. Total moles of H* = moles of H* neutralized by antacid + moles of H* neutralized by NaOH Because the antacid includes both OH and CO23, it is not possible to calculate the number of moles of each these ion species independently. Instead, the…

4mL of diluted protein solution was prepared by mixing 200uL of the protein solution with 3.8mL of distilled water. 100uL of this diluted was then mixed with 900uL of Lysozyme solution. Lysozyme activity was measured at 450nm and gave a reading of -0.080 (Abs/min). Calculate the concentration of lysozyme activity in units of abs/min/mL.
