Second, we designed two experiments that demonstrate the porosity of MOFs without resorting to prohibitively expensive or complex tools. As early as 1949 the Journal of Chemistry Education published a teacher demonstration of gas adsorption using activated charcoal, activated alumina, and silica gel. More recently, in 2014, Cheung published teacher demonstrations to show gas adsorption using zeolites. Inspired to not only demonstrate gas adsorption using MOFs, but also to provide a safe, hands-on experiment for students to perform for themselves, we developed a procedure that allows students to quantify the amount of CO2 gas their synthesized MOFs adsorb using a standard laboratory balance. This simple procedure can be completed in less These lab experiments support learning concepts including properties of gases, ideal gas law, states of matter, phase transitions, density, inorganic materials synthesis, carbon and its compounds, the carbon cycle, applications of chemistry, solutions, molarity, units and measurements, the electromagnetic spectrum, and spectrophotometers. An additional benefit is the use of Excel for data recording, graphing, and calculations, thus providing students exposure to and experience with computer software for analyzing experimental data.
