Schemes have been devised to substitute less toxic metals for more toxic ones. Potassium ferrate on K10 mont-morillonite clay has been used to replace potassium chromate and potassium permanganate in the oxidation of alcohols to aldehydes and ketones in 54-100% yields.153 The potassium ferrate is made by the action of sodium hypochlorite on iron(III) nitrate or by treatment of iron(III) sulfate with potassium peroxymonosulfate.154 After the oxidation, any excess oxidizing agent, and its reduced form, are easy to recover by filtration or centrifugation. In another case, manganese-containing reagents have been substituted for more toxic ones containing chromium and selenium (4.21).155 Selenium dioxide was used formerly in the first step and pyridinium chlorochromate in the second.

Acetylacetonatomanganese(III) has been made by the reaction of hydrous manganese(III) oxide on acetylacetone (2,4-pentanedione), by the air oxidation of a mixture of hydrous manganese(II) oxide and aqueous acetylacetone, and by the interaction of manganese (II) sulfate with potassium permanganate in an ammoniacal solution of acetyl-acetone. The present procedure is s. milar to the last-mentioned method. 

Iron and manganese reduction in wetland soils and aqnatic sediments is linked to organic matter decomposition. In the absence of oxygen, microbial commnnities nse a wide range of electron acceptors, inclnding nitrate, Mn(IV), Fe(III), sulfate, carbon dioxide, and several simple organic componnds. 

Nanocrystalline manganese(III) oxide MnjOj and manganese dioxide MnOj powders were prepared from potassium permanganate (KMn04) aqueous solutions by use of y-ray radiation in the presence of surfactants PVA or sodium dodecyl sulfate (SDS) and radical scavenger propan-2-ol (Liu et al. 1996,1997). 1 mol dm- sodium hydroxide was used for pH adjustment. Various ratios of individual compounds determine the stoichiometry of prepared materials. 

Sample Problem A Write a balanced equation for the reaction shown in Figure 2.1 (on the previous page). A deep purple solution of potassium permanganate is titrated with a colorless solution of iron(II) sulfate and sulfuric acid. The products are iron(III) sulfate, manganese(II) sulfate, potassium sulfate, and water—all of which are colorless. 

The iron(II), iron(III), manganese(II), and 2 hydrogen ions in the original equation are paired with sulfate ions. Iron(II) sulfate requires 10 sulfate ions, and sulfuric acid requires 8 sulfate ions. To balance the equation, 18 sulfate ions must be added to each side. On the product side, 15 of these ions form iron(III) sulfate, and 2 of them form manganese(II) sulfate. That leaves 1 sulfate ion unaccounted for. The permanganate ion requires the addition of 2 potassium ions to each side. These 2 potassium ions form potassium sulfate on the product side of the reaction.
