Original Abstract
An original experimental methodology, which provides both qualitative and quantitative insights into fundamental diffusion processes, is described and proposed for use in a variety of laboratory courses, e.g., chemical-biological engineering, materials science and physical chemistry. In the proposed experiments, transient and stationary diffusion flow of a colored solute is studied in an aqueous solution entrapped in an agarose gel matrix. Furthermore, the demonstration of the effect of the reaction between the solute and the gel matrix is illustrated through the addition of a reactive polyelectrolyte component into the gel structure. The proposed methodology is intended for higher-level undergraduate physical chemistry laboratory classes. It also has applications at many levels of materials science and engineering education, as it allows for direct and timely observation, as well as practical experience in data acquisition and analysis of basic diffusion concepts.
