Jeffery, Prentice Hall Dual Degree B.Sc (Hons)-M.Sc. in Chemistry Semester-III Chemistry Lab-IV Paper Code: DCH209 Credits: 03 06 Hrs/week External Marks:75 Duration of Exam: 06 Hrs Sessional Marks:25 A) Water Analysis 1. Determination of dissolved oxygen in water. 2. Determination of Chemical Oxygen Demand (COD) 3. Determination of Biological Oxygen Demand (BOD) 4. Percentage of available chlorine in bleaching powder. 5. Measurement of chloride, sulphate and salinity of water samples by simple titration method (AgNO3and potassium chromate). 6. Estimation of total alkalinity of water samples (CO32-, HCO3-) using double titration method. 7. Determination of total hardness of water (permanent and temporary) B) Chromatography 1. Separation of mixtures by Chromatography: Measure the Rf value in each case (combination of two compounds to be (a) Identify and separate the components of a mixture of 2 amino acids (glycine, aspartic acid, glutamic acid, tyrosine or any other amino acid) by paper chromatography (b)Identify and separate the sugars present in the given mixture by paper chromatography. C) Colorimetry 1. To verify Beer-Lambert Law for and K2Cr2O7 solution and determine the concentration of the given KMnO4, K2Cr2O7 solution. Note: 1. New experiment(s) related to the theory paper syllabus can also be performed in addition to the above list of experiments. 2. Depending on the availability of chemicals/instruments etc., any similar experiment can also be performed as substitute from the above list. Distribution of marks for the final practical exam 1. Experimental performance (45 Marks) 2. Viva-Voce (15 Marks) 3. Record file (15 Marks) Suggested Principles of Instrumental Analysis - 6th Edition by Douglas A. F. James Holler, and
