The reaction of equal molar quantities of 1-methyl-3-ethylimidazolium chloride (MEICI) with AICI~ results in the formation of a conductive ambient-temperature ionic liquid that, when investigated voltammetrically, exhibits 4.4V of electroinactivity between the reduction of MEI + and the oxidation of AICI4-. When unequal quantities of these reagents are used, however, the resulting melt has a much narrower electrochemical window due either to the formation of the acid A12CIC (which reduces to A1 at potentials that are nearly 2.0V positive of MEI § reduction) or the base C1-(which oxidizes to C12 at potentials that are 1.5V negative of AICI(oxidation). In this paper we investigate those equilibrium processes that control the chloroacidity in these ionic liquids. Specifically, we show that they undergo an acid exchange reaction A1CI((I) + AICI((I) ~ AI2C17-(/) + CF(/) K = 1.0 x 10 -16

A modification of an experiment to monitor the action of the enzyme lactase on the substrate lactose is reported. Previous techniques employed chromatography or spectrophotometry to follow the increasing concentration of glucose as the lactose is hydrolyzed. In this paper the use of commercially available glucose test strips for home diabetic care is described as a new approach for determining the glucose concentrations.
