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

Gravimetric Determination of Phosphorus in Fertilizer Samples ------------------------------------------------- Results and Discussion More than 50% of fertilizers are composed of nitrogen‚ phosphorus and potassium because these three nutrients are essential but are deficient in soils. To ensure good quality of fertilizers‚ it is significant that the amounts of these nutrients are quantified. In this light‚ gravimetric principles are of much use. The objective of the experiment is to determine

Experiment # 4a Title: Determination of the Hardness of Water from a Waterfall Aim: To determine the molarity of EDTA and to determine the hardness of water by measuring the concentrations of calcium and magnesium in a water sample by titration. Abstract: The aim of this experiment was to determine the molarity of a sample of EDTA and then to use this sample to determine the hardness of a sample of water. This was done using a titrimetric method. This was standardized using calcium chloride.

Determination of Total Carbohydrateby Anthrone Method Carbohydrates are the important components of storage and structural materials in the plants.They exist as free sugars and polysaccharides. The basic units of carbohydrates are themonosaccharides which cannot be split by hydrolysis into more simpler sugars. The carbohy-drate content can be measured by hydrolysing the polysaccharides into simple sugars by acidhydrolysis and estimating the resultant monosaccharides. PRINCIPLE Carbohydrates are
