title: Effect of temperature on the determination of aromatic nitro-compounds by coulometrically generated chromium(II).
abstract: The analytical utility of the reaction between aromatic nitro-compounds and electrogenerated chromium(II) can be extended to several previously undeterminable compounds by increasing the temperature of the reaction solution. For some substances the stoichiometry of the reduction is changed; for others the rate of reaction, along with precision and accuracy, is appreciably increased; in at least one instance the reaction becomes less satisfactory as an analytical method. Temperature is thus shown to be an important variable that may explain differences in previously reported stoichiometries.
