What mass of which reagent is left unreacted?Hydrogen peroxide is used as a cleaning agent in the treatment of cuts and abrasions for several reasons. It is an oxidizing agent that can directly kill many microorganisms; it decomposes upon contact with blood, releasing elemental oxygen gas (which inhibits the growth of anaerobic microorganisms); and it foams upon contact with blood, which provides a cleansing action. In the laboratory, small quantities of hydrogen peroxide can be prepared by the action of an acid on an alkaline earth metal peroxide, such as magnesium peroxide.
MgO2(s) + 2 HCl(aq) â H2O2(aq) + MgCl2(aq)
What amount of hydrogen peroxide should result when 1.26 g of magnesium peroxide is treated with 26.5 mL of hydrochloric acid solution containing 0.0736 g of HCl per mL?
