Manganese(VII) oxide, also known as permanganic acid and manganese heptoxide, is a chemical compound.The manganese is in its +7 oxidation state.Its chemical formula is Mn 2 O 7.. Solutions in sulfuric acid are dark green, and this is the most commonly prepared form. Due to its effectiveness in the fertilizer industry alone, its annual consumption lies in the range of thousands of tons. The decomposition of manganese heptoxide produces copious amounts of ozone. The resulting green liquid is manganese heptoxide dissolved in sulfuric acid, with potassium bisulfate impurities. The organometallic compound is mixed with any appropriate dust suppressant liquid. (1999), 47, 161–167. Its solubility properties indicate a nonpolar molecular species, which is confirmed by its structure. Why is Manganese Heptoxide so unstable? [2] The reaction initially produces permanganic acid, HMnO4 (structurally, HOMnO3), which is dehydrated by cold sulfuric acid to form its anhydride, Mn2O7. This volatile liquid is highly reactive and more often discussed than intentionally prepared.
