Ascorbic acid is unstable in solution, especially alkaline solution, readily undergoing oxidation on exposure to the air.The oxidation process is accelerated by light and heat and is catalyzed by traces of copper and iron. Ascorbic acid solutions exhibit maximum stability at about pH 5.4. Solutions...
The metal ions in the solution catalyze the oxidation of ascorbic acid independent of the oxygen concentration. (12)Cathode: 2H+(aq)+2e−→H2(g) (13)Anode: 2H2O→O2(g)+4H+(aq)+4e− (14)Cathodic reaction: 2H+(aq)+2e−→H2(g) (15)Anodic reactions: Fe(s)→Fe2+(aq)+2e−...
