Water chemistry is a fundamental discipline that explores the properties and chemical reactions of water, a molecule essential to life as we know it. Because of its unique composition and its ability to dissolve many substances, water plays a central role in a multitude of chemical, biological and environmental processes.
This water chemistry course aims to provide a thorough understanding of the fundamental principles that govern water behavior. We will explore key concepts such as water molecular structure, intermolecular forces, physical and chemical properties of water, as well as specific chemical balances related to water.
An important part of this course will focus on the calco-carbonic balance of water, which is the equilibrium system between carbon dioxide (CO₂), carbonic acid (H₂CO₃) and hydrogen carbonate ions (HCO₃^-) and carbonate (CO₃^2-). We will study the reactions that govern this balance, the factors that influence it, and the environmental and biological consequences of this balance
We will also discuss redox reactions involving water, notions of pH and acidity, buffering properties of water, and oxidation and reduction reactions that occur in aqueous systems.

This course will focus on applying theoretical concepts to concrete examples, and will provide essential tools to understand the chemical reactions that take place in aqueous solutions, as well as environmental issues related to water.

It is recommended to have a solid foundation in general chemistry and chemistry solutions to get the most out of this course. Water chemistry is an exciting and relevant discipline that will find applications in many fields including chemistry, biology, medicine, environmental engineering and many more.

Get ready to explore the fascinating world of water chemistry and develop a deep understanding of this crucial molecule that supports life on our planet. Enjoy reading and learning!

Les matériaux adsorbants jouent un rôle crucial dans de nombreux domaines de la chimie, de l'industrie et de l'environnement. Leur capacité à retenir sélectivement des molécules ou des ions à leur surface les rend indispensables dans des applications telles que la purification de l'eau, la séparation des composés chimiques, la capture des polluants et même la formulation de médicaments. Comprendre comment les matériaux adsorbants fonctionnent et interagissent avec les molécules cibles est essentiel pour développer des solutions efficaces aux défis scientifiques et technologiques contemporains.
Au cours de ce cours, vous serez amenés à explorer divers types de matériaux adsorbants, tels que des charbons actifs, des zéolithes, des polymères poreux et des argiles. Vous découvrirez comment préparer ces matériaux, les caractériser à l'aide de techniques analytiques appropriées et évaluer leurs performances en termes de capacité d'adsorption, de sélectivité et de cinétique. Vous apprendrez également à interpréter les données expérimentales pour obtenir des informations précieuses sur les processus d'adsorption et pour évaluer les performances des matériaux adsorbants.
