Environmental chemistry

• Thermodynamic reminders on chemical equilibrium in solution, the law of mass action and the principle of a dosage by equilibrium shift
• Application to equilibria:
  • acid-base: Acids and bases, Calculation of the pH of aqueous solutions, Titrations
  • of complexation: prediction of reactions, domain of predominance of species, influence of pH
  • precipitation: stability/solubility of solids, influence of pH
  • redox reactions: reminders and definitions, electrochemical cells, electrode potentials, prediction of the evolution of redox reactions
• Analytical techniques used in environmental chemistry, with applications to the determination of physicochemical parameters of water quality:

• Electrochemical techniques,
• Spectrophotometric techniques
• Chromatographic techniques
