Manganese heptoxide (\(Mn_{2}O_{7}\)) isn't typically a stable "solution" but a dangerously unstable, dark red oily liquid that forms when potassium permanganate (\(KMnO_{4}\)) reacts with concentrated sulfuric acid (\(H_{2}SO_{4}\)) and decomposes explosively on heating or contact with organics, producing permanganic acid (\(HMnO_{4}\)) in water, making it highly hazardous, not for general use.
