What is the principle of the given test for Urine reducing substance?
Ans. A. Cu2+ ions are reduced to Cu+ ions by enediols* This test is Benedicts test. The principle of the test is*Cu2+ions present in Copper sulphate is reduced to Cuprous hydroxide and later to Cuprous oxide by enediols formed from reducing sugar
Cu2+ ions are reduced to Cu+ ions by enediols
Cu+ ions are oxidised to Cu2+ ions by enediols
Fe2+ ions are reduced to Fe+ ions by enediols
Fe+ ions re oxidised to Fe2+ ions by enediols
