The use of permanent magnet [to the thirteenth power]C NMR in large-section first-semester organic chemistry lab courses is limited by the availability of experiments that not only hinge on first-semester lecture topics, but which also produce at least 0.5 mL of neat liquid sample. This article reports a discovery-based experiment that meets both…

Brigandi, Laura M.; Leber, Phyllis A.; Yoder, Claude H. – Journal of Chemical Education, 2005
A project involving the synthesis of several naturally occurring copper double salts using simple aqueous conditions is reported. The ions present in the compound are analyzed using colorimetric, gravimetric, and gas-analysis techniques appropriate for the first-year laboratory and from the percent composition, the empirical formula of each…
