Abstract
An attempt to introduce chemical equilibrium simulation software to chemical education in Wakayama National College of Technology is presented in this report. Compared to molecular modeling software, software simulating inorganic chemical systems has been rarely used in chemical education. The OLI Analyzer is well known to be useful simulation software to estimate inorganic chemical equilibrium reactions and physicochemical properties of aqueous chemical systems; therefore, we employed the OLI Analyzer as an auxiliary educational tool for lectures related to inorganic chemistry. In order to support the lectures of inorganic material chemistry, a computer simulation of the selectivity of the precipitation reaction of hydroxyapatite was demonstrated using the OLI Analyzer as an appropriate example. In a practical material science experiment, the boiling points of sodium chloride aqueous solution under several pressure conditions were also calculated to estimate the corresponding temperature elevations. The participating students were relatively interested in the practical use of the chemical equilibrium simulation, which suggests that the introduction of the OLI Analyzer might be educationally effective for lectures related to inorganic chemistry.
