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

: The Vitamin C Content of Fruit Juices Lecturer : Madam Rita Rohaizah binti Sohari TITLE: THE VITAMIN C CONTENT OF FRUIT JUICES INTRODUCTION Vitamin C which is also known as ascorbic acid is an essential nutrient for human. It is a water-soluble vitamin that is necessary for normal growth and development. Water-soluble vitamins dissolve in water. Leftover amounts of the vitamin leave the body through the urine. That means a continuous supply of vitamin is needed in daily

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:

Title : The Vitamin C content of fruit juice Aim : To investigate the vitamin C content of fruit juice. Introduction : [2]Vitamin C‚ also known as the ascorbic acid or the L-ascorbate‚ is required for the growth and repair of tissues in all parts of our body. It is necessary to form collagen‚ an important protein used to make skin‚ scar tissue‚ tendons‚ ligaments‚ and blood vessels. Vitamin C is essential for the healing of wounds as well as for the repair and maintenance of cartilage‚ bones

Feed water-soluble vitamins and minerals refer to those nutritional additives in the animal feed that fulfill the animals’ nutritional requirements while helping them in their growing‚ developing‚ and reproducing stages. Due to a number of functions–such as strengthening the bones of the animals and improving the immune system–they are gaining importance in the feed industry. This market is growing steadily due to the increasing awareness regarding animal nutrition and recent outbreaks of livestock

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

Activity 1.21- Is high Vitamin C all it claims to be? Purpose: * To investigate the vitamin C content of fruit juice * To investigate which type of fruit juice provides the most vitamin C The quantity of vitamin C in food and drink can be determined using a simple colour test. Vitamin C decolourises the blue dye DCPIP (dichlorophenolindolphenol). Vitamin C is an antioxidant and reduces the DCPIP. DCPIP changes from blue to colourless (or slightly pink) as it becomes reduced. We will
