LABORATORY FOR GENERAL AND INORGANIC CHEMISTRY
Learning outcomes of the course unit
To provide the basic concept of reactivity, identification, and separation of chemicals. Written exercitations on the subjects of General and Inorganic Chemistry. Acquisition of basic laboratory techniques. Execution of experiments for the application of the notions of General Chemistry.
Course contents summary
Written exercises on stoichiometry: atomic mass, molecular mass, mole, Avogrado’s number; rection types, chemical equations balancing; weight and volume ratios among reactants and products; determination of empirical and molecular formula; limiting reactant and yield. Applications of the ideal gas law and of the real gas law. Composition of solutions. Chemical equilibrium in gas phase. Equilibrium constants. Equilibria in solution: ionic dissociation, solubility, solubility product. Acid-base equilibria: strong and weak acids/bases; definition and calculation of pH, hydrolysis, buffer solutions. Galvanic cells. Laboratory exercitations: 1- dissolution, precipitation, and separation. Simple reactions in aqueous solution. 2- Synthesis of zinc iodide. 3- Determination of the absolute zero T value by application of ideal gas law and Dalton law. 4- Preparation and dilution of solutions with known concentration. 5- Identification of simple inorganic compounds by reactivity tests. 6- Acidimetric titrations – 7- Preparation and crystallization of a coordination compounds; preparation of a silica gel by sol-gel techniques.
