'''Mangan(VII)oxid''', Mn<sub>2</sub>O<sub>7</sub>, är en högexplosiv och starkt [[oxiderande]] [[grön]] och oljig vätska.<br />
<br />
==Egenskaper==<br />
Ämnet är svårt att förvara eftersom vätskan kan övergå till [[gas]] och antända papper eller andra [[brännbara]] ämnen. Mangan(VII)oxiden smälter vid 5,9&nbsp;°C och sönderdelas explosivt vid uppvärmning till [[mangandioxid]] (MnO<sub>2</sub>) och [[ozon]] (O<sub>3</sub>).<br />
:<math>\rm Mn_2O_7 \rightarrow 2\ MnO_2 + O_3</math><br />
<br />
==Framställning==<br />
Mangan(VII)oxid tillverkas genom att låta [[svavelsyra]] (H<sub>2</sub>SO<sub>4</sub>) reagera med [[kaliumpermanganat]] (KMnO<sub>4</sub>).<br />
:<math>\rm 2\ KMnO_4 + 2\ H_2SO_4 \rightarrow Mn_2O_7 + H_2O + 2\ KHSO_4</math><br />
<br />
Det är en mycket farlig reaktion och den kan lätt explodera av sig själv eller reagera med många organiska material.<br />
