3 ENGINEERING CHEMISTRY-II PRACTICAL CONTENTS Intellectual Skills: 1. Study the effect of heating on materials and reagents. 2. Study of the reactions of the following radicals leading to qualitative analysis of the given Inorganic simple salt soluble in water or dilute acids. Acid radicals: Chloride, Carbonate, Sulphate and Nitrate. Basic radicals: Lead, Copper, Aluminium, Zinc, Barium, Calcium, Magnesium and Ammonium. Motor Skills: 1. Handling the apparatus Care fully. 2. Industrial safety. I. Analysis Of Inorganic Simple Salt: The Students may be asked to analyse eight inorganic simple salts containing any of the acid and basic radicals in each salt without omitting any of the above mentioned radicals and write the analysis in record book mentioning the name of the salt. II. Analysis of effluents containing the following metal ions - Lead, Copper, Cadmium and Zinc. Students may be given above four pollutants, in four separate test tubes in solution form and asked to report metallic pollutants with procedure (Basic Radical Analysis Procedure) and their harmful effects. Note: All the students are given same Questions and each student is given one Inorganic simple salt and one effluents containing one basic radical.
