Summary

Virtual ChemLab: General Chemistry v.2.5 is an easy-to-use simulation of five different general chemistry laboratories. These laboratories include Inorganic Qualitative Analysis, Fundamental Experiments in Quantum Chemistry, Gas Properties, Titration Experiments, and Calorimetry. These laboratories can be used to replace or supplement a wet lab, for pre-laboratory or post-laboratory activities, for homework or quiz assignments, or for classroom demonstrations. The experimental results and outcomes for each laboratory are based on extensive experimentally determined databases and models. Book jacket.
