For M²*/M and M³*/M²+ systems, the values for some metals are as follows: Cr2+/Cr -0.9V Cr³/Cr²+ -0.4 V Mn2*/Mn-1.2V Mn³+ Mn²+ +1.5 V Fe²+ /Fe -0.4V Fe/Fe²+ +0.8 V Use this data to comment upon: (i) The stability of Fe³+ in acid solution as compared to that of Cr³+ or Mn³+ and (ii) The ease with which iron can be oxidised as compared to a similar process for either chromium or manganese metal. For M²*/M and M³*/M²+ systems, the values for some metals are as follows: Cr2+/Cr -0.9V Cr³/Cr²+ -0.4 V Mn2*/Mn-1.2V Mn³+ Mn²+ +1.5 V Fe²+ /Fe -0.4V Fe/Fe²+ +0.8 V Use this data to comment upon: (i) The stability of Fe³+ in acid solution as compared to that of Cr³+ or Mn³+ and (ii) The ease with which iron can be oxidised as compared to a similar process for either chromium or manganese metal.
