A 5.00 ml sample of filtered orange juice was treated with 50.00 mL of 0.01019 M I3 to oxidize ascorbic acid to dehydroascorbic acid. After the oxidation was complete, excess 13- was back- titrated with 13.96 ml of 0.07125 M Nazs203 to starch indicator endpoint. What is the concentration of ascorbic acid (MM = 176.12) in the orange juice? Report the concentration ascorbic acid in mg/100mL. C6H8O6 + 13 - C6H6O6 + 31" + 2H* 13 + 282032 - S406?- + 312
