Transformation of matter 2
Description
The course is divided into four parts :
• Thermochemistry, chemical equilibrium : thermodynamical variables, energy, entropy, enthalpy, equilibrium constant, Le Chatelier principle, Gibbs phase rules.
• Acidobasicity : Brönsted acid/bases. pH of aqueous solutions. Acid/base Strength : pKa, pH indicators, buffers and indicators titrations.
• Redox reactions : oxidizers/reducers, half reactions, cells, potential, Nernst equation
• Solubility, complexation and precipitation : solubility equilibrium and product, ions in solution, electroneutrality, complexation equilibrium
