Vitamin C content in nutraceutical fomulation can be detemined by 2,6- dichloroindophenol titrimetric method. Determine the concentration of vitamin C (mg/g) in the nutraceutical formulation using the following information. Sample weight of 101.7 g, diluted to 500 mL with phosphoric acid and acetic acid and the solution is filtered. 25 mL of the filtered sample is titrated by using the above method. The volume of dye used for the test solution and blank titration are 9.20 mL and 0.10 mL. 1.0 mL of indophenol standard solution is equivalents to 0.175 mg/mL of ascorbic acid.
