titration use. 2. To find out the concentration of Vitamin C in the tablet. Theory: This experiment involves titration of redox reaction. Redox reaction means reduction and oxidation. In which oxidizing agent and reducing agent are mixed and oxidize/reduce each other. One losses electron(s) and increase in oxidation number when is oxidized‚ and vice versa. In order to find out concentration of the ascorbic acid in the tablet‚ a redox reaction of it with iodine was done. While iodine is an oxidizing

Finally the Android* Tablet 100% TUNISIEN!!! It was exposed for sell at the SIB from the 29th November till the 3rd of December for only 499 dt. The Tablet was designed by three engineers‚ to think‚ realize and finally release the product. These engineers were graduated from Tunisian universities. It only took them 5 months so that their product shows up in its first test version. It was an enormous pleasure to discover its characteristics. It is a team of four engineers namely: • Chiheb Bouattour:

Analysis of Commercial Vitamin C Tablets Aim: To employ iodometric titration to determine the content of vitamin C in commercial tablets using volumetric analysis and compares it with the manufacturersÂ’ specifications. Introduction Vitamin C is an essential substance for maintaining good health and it is proved to be the agent which prevents scurvy. Most animals can synthesize their own vitamin C‚ but some‚ such as human cannot. Owing to the increasing concern for oneÂ’s health

Analysis of commercial vitamin C tablets Objective To determine the vitamin C content in commercial vitamin C tablets by titration between vitamin C (ascorbic acid) & iodine solution. Hence‚ compare this data with the manufacturer ’s specification. Principle In this analysis‚ certain amount of iodine solution‚ which is known in excess‚ is added to acidified ascorbic acid solution. Brown iodine can be easily reduced by acidified ascorbic acid to form colourless iodide ion:
