Provide a balanced equation for the oxidation of the following: 2-propanol to acetone by means of Cr2O7-2/H+. Please show all steps to obtain the final balanced equation.
Iron (II) ions catalyze the oxidation of luminol. The intensity of the resulting chemiluminescence has been shown to increase linearly with iron (ii) concentration from 10^-10 to 10^-8 M.
