As vitamin C is oxidized, the DCP is reduced and gains the two hydrogen atoms lost by the vitamin. As the DCP is reduced, it changes from red to colorless. Since the reaction between the DCP and vitamin C is very fast, this color change can be used to indicate the point in a titration at which all of the DCP has just been consumed by the vitamin.Titration is also used to determine the estimated chain length of fatty acids in a fat. Other uses of titration in the food industry include tests for the amount of salt or sugar, and the concentration of vitamin C or E, in a product.

Vitamin C, more properly called ascorbic acid, is an essential antioxidant needed by the human body (see additional notes). When iodate ions (IOFrom the titration equation (below) determine the For vitamin C tablets: Dissolve a single tablet in 200 mL moles of ascorbic acid reacting. of distilled water (in a volumetric flask if possible). ascorbic acid + I2 → 2 I− + dehydroascorbic acid For fresh fruit juice: Strain the juice through cheese cloth to remove seeds and pulp which may block 5. nieuport 28 They walked Toy back onto the hall, and he went quietly, meekly.
