Walter Weizel "Ruprecht-Karls-Universität Heidelberg". He received his doctorate in physical chemistry at Heidelberg, under Max Trautz. He switched form chemistry to physics to work on the quantum mechanics of molecules as a fellow of the "Notgemeinschaft der Deutschen Wissenschaft" (NG; Emergency Association of German Science) at the "Universität Rostock". He completed his Habilitation in 1929. After Habilitation, Weizel worked briefly at "Badische Anilin- und Sodafabrik" (BASF, Baden Aniline and Soda Factory) at Ludwigshafen. Then, during 1931, he had a Rockefeller fellowship to the University of Chicago. From late in 1931, Weizel was an "ordentlicher Professor" (ordinarius professor) of theoretical physics at the
Club soda water in stain removal. Club soda Club soda is a manufactured form of unflavored carbonated water, commonly used as a drink mixer. Potassium bicarbonate and/or potassium sulfate and/or sodium citrate are artificially added to replicate constituents commonly found in natural mineral waters Seltzer water is a similar manufactured carbonated water, but lacks added mineral content. The popular belief that carbonated water is a good remover of clothing stains, particularly those of red wine, is based on hearsay and anecdotal evidence. The dissolved gas in water acts as a temporary surfactant. There is no underlying chemical reason why carbonated water would
