The test is a detection method for monosaccharides, specifically aldoses and ketoses. These are detected when aldehyde oxidizes to acid and forms a cuprous oxide. Upon contact with an aldehyde group, it is reduced to cuprous ion, which forms the red precipitate and inedicates the presence of reducing sugars. The rules for balancing redox reactions include that electron must be canceled out when adding and stoichiometry are done. If the first reaction is multiplied by 2 and the second by 5, then the two are added together we get the balanced, overall redox reaction: 5C 2O 4 2-+ 2MnO 4-+ 16H+ 10CO 2 + 2Mn 2+ + 8H 2O This reaction tells us that five ...
