Chemical Properties | superacid; moisture sensitive [KIR78] [ALD94] Strongest superacid known mixture of HF and SbF5 (1:1 is strongest) Protonate even hydrocarbons to afford carbocations and H2. 2×1019 (20 quintillion) times stronger than 100% sulfuric acid. Ho values of -31.3 | Uses | Hydrogen hexafluoroantimonate(V) is an excellent medium for the preparation of alkylidene oxonium salts. | Preparation | Fluoroantimonic acid is produced by reacting hydrogen fluoride (HF) with antimony pentafluoride (SbF5). SbF5+HF→SbF6+HF | General Description | HF/SbF5 may be synthesized by mixing hydrogen fluoride and antimony fluoride.1 Fluoroantimonic acid (HF/SbF5), is a combination of SbF5 and HF. It is the known strongest liquid superacid. |
