Which species is classified as a Arrenhius base? 1. CH3OH 2. LiOH 3. PO43- 4. CO32-

2. LiOH

Explanation:

An Arrhenius base is a substance or chemical compound which increases  the number of OH- ions when added in water.

LiOH or lithium hydroxide is one of the strong Arrhenius base as it ionizes completely or near-completely in solution. When LiOH is added to water , it dissociates into lithium (Li+) and hydroxide (OH−) ions.

Hence, the correct answer is 2. LiOH.
