Turns abstract Kinetic Theory concepts into visual images, easily understood. Spectroscopy in Large Lecture Halls Procedure Shows the color spectra of white light and the spectral lines of neon. Combustion of Acetylene Procedure Acetylene is generated with calcium carbide and HCl and ignited with bleach. Generates an explosion with flameball. Thermite Procedure Ferric oxide and aluminum powder are ignited with an Mg fuse in clay flower pots.
Molten iron drops from the pots into a dish of sand.
Explain buffer solutions as the color change slows. One liquid is added dropwise to another, forms a precipitate. Can be done with precipitates of different colors. Views nicely on the overhead projector using large well plates, but the color of the precipatates doesn't project. Large flasks show colored precipatates well for large lecture halls.
