antimony pentafluoride

Antimony pentafluoride is a highly toxic, colourless, and viscous liquid known for being one of the strongest Lewis acids. In the context of superacids, it acts as an agent that binds to the conjugate base of a Brønsted acid, leaving the proton entirely unencumbered. This synergistic effect creates some of the most corrosive and reactive chemical systems known to science.
