4. Using the average moles of vitamin C titrated, calculate the amount of vitamin C, in mg, that was in the tablet you analyz
average mol vitamin C titrated =1.454x10^-4
when prepared 5.0ml of vitamin C was added to a mixture of 5ml 0.6M KI, 5.0 ml 1.0M HCL and 1.0 ml starch indocator.

Answer #1

The molar mass of Vitamin C is : 176.14 g/mol

Average mass of Vitamin C = Average moles of Vitamin C * Molar mass = 1.454 * 10-3 * 176.14 = 25.61 * 10-3 g = 25.61 mg

    Ascorbic acid (vitamin C, MM 176.124 g/mol)) can be determined using an iodometric back titration. A vitamin C tablet was dissolved in 60 mL of 0.3 M H2S04. To the dissolved tablet, 2 g of KI and 50.00 mL of 0.0105 M KIO3 were added, resulting in the formation of a dark orange solution indicating the presence of 13-. The resulting solution was titrated with 0.0685 M S2032- until the starch indicator turned purple. If the end point was observed...
