concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to the oxidizing agent‚ and the triiodine is titrated with stand thiosulfate. This indirect analysis finds the number of moles of ascorbic acid based on the known number of moles of IO3- and subtracting half the amount of moles of the thiosulfate solution.

Vitamin C Molecule Investigation Thomas Philpott Introduction Vitamin C (ascorbic acid) is an essential component of human nutrition‚ as it is an antioxidant that the body requires. Having a deficiency in Vitamin C can lead to scurvy‚ a disease characterized by abnormalities in human bones and teeth. Fruits and vegetables are common sources of Vitamin C‚ notably oranges and citrus fruits. Cooking and the application of heat destroy the vitamin so such fruits must be raw in order to obtain the

Quan Chapter 15: Redox Titrations 1. (A) Which of the following is true of a redox titration? (i) Since the redox reaction is spontaneous‚ the equilibrium constant does not have to be large for an effective titration. (ii) The titration effectiveness is increased when the two half-reaction potentials are far apart. (iii) Without an indicator the equivalence point cannot be detected. (iv) For an effective redox titration‚ the reducing agent must always be in the buret. (v) The equivalence
