Find answers to questions asked by student like you. Problems encountered with the use of large quantities of chromium trioxide, which is toxic and dangerous for the environment, prompted the development by Zhao [8] of a catalytic procedure, involving treatment with excess of periodic acid (H5IO6) in presence of about 1.2 mol% of CrO3. Write the chemical equation for the reaction to which this value… KMnO 4 can oxidize many inorganic compounds.
