Question

Is $\mathrm{KOH}$ an Arrhenius acid or base?

Answer 1

Explanation:

1. Arrhenius Acid: The compound which give ${\mathrm{H}}^{+}$ ion in their aqueous solution is called Arrhenius acid. Example- $\mathrm{HCl}$
2. Arrhenius base: The compound which give ${\mathrm{OH}}^{-}$ ion in their aqueous solution is said to be Arrhenius base. Example- $\mathrm{NaOH}$
3. $\mathrm{KOH}$ will give ${\mathrm{OH}}^{-}$ ion in its aqueous solution so it is a base.

Hence, $\mathrm{KOH}$ is an Arrhenius base.
