In the libratory, small quantities of hydrogen peroxide can be prepared by the action of an acid on alkaline earth metal peroxide, such as barium peroxide:
Ba02(s)+2HCl(aq)---->H2O2(aq)+BaCl2(aq)
Hydrogen peroxide is used as cleaning agent in the treatment of abrasions and cuts for several reasons. It is an oxidizing agent than 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.
Explain what amount of hydrogen peroxide should result when 1.50 g of barium peroxide is treated with 25.0 ml of hydrochloric acid solution which is having 0.0272 g of HCl per ml?
