Determination of Vitamin C Concentration by Titration (Redox Titration Using Iodate Solution) Introduction This method determines the vitamin C concentration in a solution by a redox titration with potassium iodate in the presence of potassium iodide. Vitamin C‚ more properly called ascorbic acid‚ is an essential antioxidant needed by the human body (see additional notes). When iodate ions (IO3−) are added to an acidic solution containing iodide ions (I−)‚ an oxidation-reduction reaction occurs;

not‚ the majority of fruits‚ vegetables and flowers contain pigments which may be used as acid-base indicators. For example‚ Red cabbage contains within its leaves a red pigment called anthocyanin. This is present in many other vegetables such as capsicum‚ carrot‚ tulips and many more. This anthocyanin has the ability to change colour in a variety of pH due to certain chemical reactions that take place involving H+ and OH- ions. Read on to discover the chemistry involved in these reactions. Anthocyanins
