Description

The aim of this solution chemistry course is to introduce the various concepts needed to study the complex liquid mixtures used in separative chemistry. The proposed approach is mainly thermodynamic. In particular, we explain the role of concentration effects, beyond the ideal laws valid only for dilute solutions.

Syllabus

I General thermodynamics applied to solutions

Donder's criterion - LAM - central role of chemical potential - Ideal solution - Ideal mixture - Quantity characterizing the composition of a mixture - effects of activity coefficients - experimental measurement of activity coefficients - Gibbs-Duhem equality -

Application: cmc measurement, practical example of activity measurement for lanthanide salts - comparison of equilibria in - micellization models

 

II Acid-base balances and the role of concentration

Interest of pH for speciation - experimental methods - Role of solvents - case of concentrated solutions - The case of water: pOH and preponderant role of hydroxides

Applications: Separation of actinides by acid extractant, solubility of metal ions

 

III Redox equilibria and speciation diagrams

Redox course reminders - Pourbaix diagrams - plotting and use

Applications: the relatively simple case of the lanthanides, the much more difficult case of the actinides

 

IV Complexation equilibria

Ligands and solvation - Successive equilibria - Classification of ligands - enthalpic and entropic factors - pC

Applications: transition elements - supramolecular chemistry and separation chemistry - generalized speciation diagrams

 

V Precipitation equilibria

Solubility - Competition between ionic species - solid solutions - kinetic factors

Application: Berthelot-Nernst and Doerner Hoskins coprecipitation.
