Manganese(VII) oxide facts for kids

Manganese(VII) oxide, also called permanganic acid or manganese heptoxide, is a special chemical compound. It's known for having manganese in a very high oxidation state of +7. Its chemical formula is Mn₂O₇. This compound is one of the few manganese compounds with a +7 oxidation state that isn't a permanganate.

Manganese(VII) oxide looks like a dark red or dark green oily liquid. It is a very strong oxidizing agent, which means it can cause other substances to lose electrons. Because of this, it is also a dangerous explosive.

How it is Made

Manganese(VII) oxide is made by mixing sulfuric acid with potassium permanganate. When these two chemicals react, they create the dark green oily substance that is manganese(VII) oxide.

What it Does

This compound is very unstable. If it explodes, it breaks down into manganese dioxide and oxygen. Sometimes, this reaction can also produce ozone, which is another strong oxidizing agent.

Manganese(VII) oxide can explode if it is hit or if it comes into contact with certain organic substances, like alcohol. Because it is so dangerous, it must be handled with extreme care.
