← ScienceWhich outcome occurs when hydrogen fluoride (HF) dissolves in water and donates a proton?
A)Increase in fluoride ion concentration✓
B)Formation of metallic hydrogen clusters
C)Depletion of hydroxide ions
D)Precipitation of calcium fluoride
💡 Explanation
When HF dissolves and donates a proton, it undergoes acid dissociation because the hydrogen-fluoride bond breaks heterolytically, forming hydronium ions and fluoride ions. Therefore, fluoride ion concentration increases, rather than metallic clusters, hydroxide depletion, or precipitation, which depend on different counter-ions and mechanisms..
