Learning outcomes
At the end of the course the student will possess the knowledge and the theoretical basis necessary for the understanding of the quantitative aspects of the chemical reactions. The student will be able to describe the equilibria involved in chemical transformations through the use of stoichiometric equations and to evaluate the spontaneity of acid-base, redox and precipitation reactions, as well as to understand the meaning of the experimental results in various quantitative analysis, especially those based on volumetric titrations.
Course contents
Use of different definitions of concentration of solutes in
homogeneous and heterogeneous mixtures. Molarity, molality and
molar fraction. Percentages by weight and volume.
Tutorials on convertions between different expressions of
concentration.
Preparation of solutions of known titre, cross calculation.
Acid-base reactions. Redox reactions. Balancing chemical reactions
at the base of food transformations and use of stoichiometric
coefficients.
Reagents in excess or defect and calculation of the yield of
conversion.
Solubility and solvation. Colligative properties. vapor pressure
lowering, boiling point elevation, freezing point depression,
osmotic pressure.
Weak acids and weak bases. Redox species.
Acid-base and redox titrations. Normality.
The product of solubility. The effect of the ion in common.
Simultaneous equilibria in solution. The buffer solution.
Computer-aided problem solving stoichiometric
