In the given reaction: SbF_5 + BrF_3 BrF_2^+ + SbF_6^- Step 1: Analyze the transfer of species. In this reaction, BrF₃ donates a fluoride ion (F⁻) to form BrF₂⁺. BrF_3 → BrF_2^+ + F^- SbF₅ accepts this fluoride ion (F⁻) to form SbF₆⁻. SbF_5 + F^- → SbF_6^- Step 2: Determine the role of SbF₅. According to the Lewis acid-base theory, a Lewis acid is a species that accepts an electron pair. In the context of fluoride ion transfer, a species that accepts a fluoride ion (which carries an electron pair) acts as a Lewis acid. Since SbF₅ accepts a fluoride ion, it is acting as a Lewis acid. Step 3: Compare with the given options. A: buffer - A buffer resists changes in pH. This is not the primary role here. B: indicator - An indicator signals the presence of a substance or a change in conditions. This is not the role here. C: base - A base is an electron pair donor or a proton acceptor. SbF₅ is an acceptor, not a donor. D: acid - An acid is an electron pair acceptor or a proton donor. SbF₅ acts as an electron pair acceptor (specifically, a fluoride ion acceptor), which classifies it as an acid (Lewis acid). The correct option is D. The final answer is D:acid. What's next? 📸
