Not sure about the above statement that oxygen is a reducing agent. In chemistry, an oxidising agent ( oxidant, oxidiser) is a substance that has the ability to oxidise other substances. Common oxidising agents are oxygen and hydrogen peroxide. If you want to see how hydrogen peroxide works, drop a very small piece (less that half fingernail size) of raw steak in a tablespoonfull of hydrogen peroxide. The bubbles released contain oxygen which is the active ingredient in oxidising the stain. If you want to speed up this experiment, use a piece of raw liver the same size as the steak - and stand back!
