| Description:
| Aims: To develop basic concepts of liquids and solutions including: a thermodynamic description of colligative properties, non-ideal behaviour, dielectric properties, electrolytes, fundamentals of solvation as well as some examples of liquids and solutions in context including liquid crystals, solutions of polymers and dynamic electrochemistry. Learning Outcomes: * Describe a liquid and a mixture of liquids in terms of its thermodynamic properties; * Explain the effect of a solute on the freezing and boiling point of a liquid; * Describe the dielectric properties of water and some non-aqueous polar solvents; * Describe the hydration and solvation of ions; * Describe the molecular structure found in common liquid crystals; * Application of examples from electrochemistry as well as pure liquids and liquid mixtures to solve chemical problems. Skills: Problem-solving (T,A), Numeracy (F,A), Independent working (F). Content: * Thermodynamic properties of pure liquids and liquid mixtures (non-electrolytes) * Partial molar quantities * The vapour pressure of liquid mixtures * Colligative properties - the effect of solute on the boiling and freezing points * Non-ideal mixtures * Dielectric properties - and examples water and non-aqueous polar solvents * Activities, regular solutions * Aqueous solutions of electrolytes - hydration, solvation of ions, Debye-Huckel theory, ionic transport and the ionic atmosphere * Liquid crystals - order and molecular structure * Solutions of polymers * Dynamic electrochemistry - voltammetry, electrode kinetics. |
