Lab Report: MEASUREMENT OF VITAMIN C Introduction Nutritional diseases were once the number one cause of death only a century ago‚ but rarely affect our lives today. The complete lack of vitamin C (ascorbic acid) characterized by dark purple spots on the skin and rotting gums‚ a disease called scurvy‚ took the lives of many sailors up until the mid 1800s when the prevention was discovered. Consequently‚ British sailors became referred to as ‘limeys’ because of their daily habit of eating

Control Systems Lab Project (Ball and Beam) Ball and Beam Abstract The ball and beam system can usually be found in most university control labs since it is relatively easy to build‚ model and control theoretically. The system includes a ball‚ a beam‚ a motor and several sensors. The basic idea is to use the torque generated from motor to the control the position of the ball on the beam. The ball rolls on the beam freely. By employing linear sensing techniques‚ the information from the sensor

Oxidation Reduction Titrations: The Indirect Iodimetric Analysis Ascorbic Acid Unknown Number 69 I: Purpose: To determine the percent weight of Ascorbic Acid in unknown sample. This was to be done by the means of an indirect iodimetric analysis. In an iodometric analysis‚ the oxidizing agent can be determined by a different means than titrating directly with standard iodide‚ because a high concentration of I- is needed to form the I3- complex. In this type of analysis‚ excess iodide is added to

DETERMINATION OF VITAMIN C CONTENT IN COMMERCIAL (CENOVIS) TABLET ABSTRACT In this experiment‚ the vitamin C content of a commercial tablet is determined and compared with the manufacturers’ specification. Vitamin C is water-soluble and is an enantiomer of ascorbic acid. (Commercial vitamin C is often a mixture of ascorbic acid and other ascorbates.) Ascorbic acid‚ C6H8O6‚ is a reducing agent that reacts rapidly with iodine (I2). As the iodine is added during the titration‚ the ascorbic acid is

In flask A 25.0 mL KI solution was added in a flask using a graduated cylinder. 2 separate 1 mL pipettes were used for measuring 1.0 mL Na2S2O3 and starch solutions (Department of Chemistry and Biology‚ 2012). These 2 solution were also added to flask A. 48.0 mL KNO3 solution
