Laboratory Safety Measures (6 Hours)
Handling of hazardous chemicals, incompatible chemicals, flammable solvents, fire hazards in chemical laboratory, control of fire, fire extinguishers, toxicity of chemicals, forms of toxic materials, personal protective equipment, health effects and first aid, MSDS (material safety data sheet), use of compressed gases, waste minimization strategies and chemical waste disposal, procedures for neutralization of strong acids and strong bases.
Volumetric Analysis (54 Hours)
Classification and primary requirements of titrations, concept of normality and molarity.
Acid-base titrations: basic principle, neutralization indicators- types, theories of indicators, choice of indicators, titration curves and applications.
Redox titrations: Principle, indicators, and applications of permangnatometry, dichromatometry, iodometry titrations, redox equations, standard electrode potential and its application to inorganic reactions.
Calibration of fractional weights, pipettes and burettes, preparation of standard solutions, dilution – 0.1 M to 0.001 M solutions, buffer solutions.
