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.

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
