A Simple Explanation of Complexation

Abstract

The topics of solution thermodynamics, activity coefficients, and complex formation are introduced through computational exercises and sample applications. The presentation is designed to be accessible to freshmen in a chemical engineering computations course. The MOSCED model is simplified to explain complex formation in terms of hydrogen bonding. In the current work, the acidity and basicity parameters are adopted directly, but the polarity and dispersion parameters are lumped together. In this way, the contrast between the physical interactions and the chemical interactions is more readily apparent. Examples are given of ConcepTesting, exam, and homework problems.
