Syllabus
Aqueous solution
Microscopic interpretation of the dissolution of a solute
Notion of strong and weak electrolyte
Conductimetry and application to conductimetric titration: interpretation of the slope change before and after titration
Equilibrium state
Activity of solutes, reaction quotient, equilibrium constant in relation to thermodynamics
Prediction of a state of progress, knowing how to determine the equilibrium state of a system undergoing a predominant reaction
Acid-base equilibrium
Concept of acid-base (Brönsted-Lowry, Lewis)
Acid-base reaction : amphoteric nature of water, leveling effect of solvent, acid and base strength
Predominance diagram, prediction of acid-base reactions
Calculate the pH of a solution and a mixture of acid and base and of a mixture by the predominant reaction method
Interpretation of a pH-metric titration curve : exploitation of equivalence, writing of the titration reaction, interpretation in the case of multiple acidities titrated separately or simultaneously
Precipitation reaction
Definitions, solubility product, displacement of precipitation equilibria, competitive precipitation, precipitation and pH
Predict the saturation or non-saturation state of a solution, solid or gas.
Use solubility evolution curves as a function of a variable.
Redox reaction
Redox couple, electrode potential, Nernst's law
Oxidation number: definition and calculation
