← ScienceWhich outcome occurs when hydrogen difluoride anion (HF₂) forms in a solution of hydrofluoric acid?
A)Increased electrical conductivity✓
B)Precipitation of insoluble fluoride salts
C)Decreased solution density
D)Formation of explosive peroxide compounds
💡 Explanation
When HF₂ forms, autoionization of HF is enhanced, forming mobile H⁺ which increases proton conductivity because this is a charged ion. Therefore increased electrical conductivity results, rather than precipitation, density change, or peroxide creation, which require alternative reaction pathways and different conditions.
