How does the partial dissociation of hydrofluoric acid affect its conductivity compared to hydrochloric acid?

• A. Both have similar conductivity because they both dissociate completely.
• B. Hydrofluoric acid does not conduct electricity at all, unlike hydrochloric acid.
• C. Hydrofluoric acid has higher conductivity because it partially dissociates, unlike hydrochloric acid which completely dissociates.
• D. Hydrofluoric acid has lower conductivity because it partially dissociates, unlike hydrochloric acid which completely dissociates.

Answer: (D)
