Lessons in Thermodynamics of Solutions and Liquid Mixtures

Review by David Bradley

Chemists at Leicester University, England, have built an educational website covering all aspects of thermodynamics in 300 topics. If I remember rightly from my University days, thermodynamics was one of the tougher areas of chemistry to master, but once you had it  covered many other aspects of the subject fell into place. To quote from the introductory section to this new site: "Thermodynamics offers an elegant summary of the experience gained by chemists in chemical laboratories and an indication of how experimental data can be analysed to gain an understanding of chemical reactions. For the most part chemists are concerned with the properties of solutions in the context of (i) chemical equilibriums, and (ii) chemical reactions between solute molecules, thereby synthesising new chemical substances. Underlying these important phenomena, chemical equilibriums and spontaneous chemical reactions, are quantitative statements based on chemical thermodynamics". If you've been struggling with your enthalpies and entropies, then this is the place to go to help you grasp those concepts.
