Ascorbic acid is titrated with iodine to the appearance of a starch endpoint color. A calibration curve is recommended. Iodine is toxic and stains skin and clothing. The room must be well ventilated. Avoid ingestion and inhalation of iodine. Wear goggles and apron. Wash hands after the experiment. This procedure describes two alternate methods for using a standard. Three titrations of one standard solution may be used if the range of vitamin C in your samples is close to the concentration of the standard. Prepare a standard curve if the concentration of vitamin C varies considerably. Use the method suggested by your instructor. Obtain a fresh solution of ascorbic acid from the instructor. the concentration should be known to 3 significant figures, and should be about 1 mg/mL. Use a calibrated plastic pipet to add 1.00 mL (or 20 drops) of this solution to a well of a 24-well plate. Add 1 drop of starch solution. Sorry, your browser does not support mp4 format video.




Try a different browser. Add iodine solution dropwise from a plastic transfer pipet with a restricted tip while counting the drops. Mix with a toothpick. Continue adding until a blue color appears that is not discharged by stirring. Repeat this procedure two more times. Continue until consistent values -- titrations that agree within 1 drop -- are obtained. An alternative procedure is for 4 or 5 solutions of known ascorbic acid concentration to be available -- with concentrations in the range from 0 to 1 mg/mL. Obtain a concentrated standard or 5 different standards from the instructor. If one concentrated standard is dispensed, make dilutions of the standard at 5 different concentrations. Titrate each of the 5 solutions to a blue endpoint. Plot a graph of mg/ml of ascorbic acid versus drops of I2 solution. Use a computer graphing program if one is available. Use a calibrated plastic pipet to add 1.00 mL of juice to a well of a 24-well plate. Any juice in which a starch endpoint can be detected will be satisfactory.




Add 1 drop of starch solution. Add iodine solution dropwise from a plastic transfer pipet with a restricted tip while counting the drops. Continue adding until a blue color appears that is not discharged by stirring. Repeat 2 more times. Rinse the 24-well plate at the sink with running water. Determine the number of mg ascorbic acid per drop of I2. Determine the number of mg ascorbic acid per mL of juice. Name ___________________________ Class ________ SmallScale 54 Vitamin C in Fruit Juices Watch the movies, and use the data below to answer the questions. Use this experiment when studying oxidation-reduction, solution stoichiometry, assays, or biochemistry. The experiment works well in regular and in applied chemistry classes. Teachers recommend using this experiment with a calibration curve. Teacher Preparation: 15 minutes Class Time: 30 minutes The materials used in this experiment may be disposed of safely at the sink. If a computer and a graphing program are available, plot the calibration data and use a line fitting feature to determine an equation for the line.
