Iron(III) is polarographically reduced to iron(II)at potentials more negative than about +0.4V versus SCE and is further reduced to iron(O) at -1.5V (vs SCE). Iron(II) is also reduced to metal at -1.5V. A polarogram is run using a dropping mercury electrode on a solution containing both Fe3+ and Fe2+.A current is recorded at zero applied volts, and its magnitude is 12.5μA. A wave is also recorded with E1/2 equal to -1.5V versus SCE, and its height is 30.0μA. Calculate the relative concentrations of Fe3+ and Fe2+ in solution.
What purpose does Acetic Acid serve in the hypochlorite oxidation of cyclohexanol? What advantages does the hypochlorite oxidation offer over conventional methods such as chromium oxidation?
When making a plot with the Claussius Clapeyron equation, the enthalpy of vaporization can be calculated from the slope of the line of lnP vs 1/T.
