Which would be the Arrhenius acid and Arrhenius base between HF and KOH

HF is the Arrhenius acid and KOH is the Arrhenius base.

Explanation:

An Arrhenius acid dissociates in water to form H + ions in solution.

An Arrhenius base dissociates in water to form OH - ions in solution.

Write the equations by breaking the compounds into their elements

HF→ H⁺ + F⁻ HF produces H⁺ when added to water, so it is the acid.

KOH→ K⁺ + OH⁻ KOH produces OH⁻ when added to water, so it is the base.
