SYLLABUS- B.Sc. CHEMISTRY PRACTICAL-I,

Lab course
1. Laboratory hazards and safety precautions.
2. Mixture analysis: preparation of sodium carbonate extract, identification of Acid Radicals (anions) including anions in combination. Home assignments: problems based on Law of mass action, Le Chatelier Principle; common ion effect, solubility product, pH and buffer solutions, mole concept, molar solution, normal solution, molarity, molality and formality, Calculation for the preparation of standard solutions of acids and bases.
3. Determination of viscosity and relative viscosity of given liquids using Ostwald's viscometer.
4. Volumetric exercise: acid-base titrations; preparation of a solution in normal/molar terms, its standardization using a primary standard solution, determination of the strength of unknown solution. For example: preparation of NaOH solution (secondary standard say N/10), preparation of (COOH)2 solution (primary standard say N/10), standardization of NaOH solution titrating it against (COOH)2 solution using phenolphthalein (indicator) and then determination of the strength of given HCl solution.
One exercise each from inorganic mixture (qualitative 04 anions), physical chemistry experiment and volumetric exercise (quantitative) shall be given in the examination.
Distribution of marks shall be as given below:
A. Inorganic mixture for acid radicals
B. Physical chemistry experiment
C. Volumetric exercise
D. Viva
E. Home assignment/internal assessment, lab record and attendance
