Answer #1

Answer:- LiOH

An Arrhenius base is defined as “any species that when dissolved in aqueous solution increases the concentration of hydroxide ions”

Lithium hydroxide dissociates in water as follows:

LiOH(aq) → Li​+​​(aq) + OH​−​​(aq)

In water, Lithium hydroxide fully dissociates to form hydroxide ions, resulting in an increase in the concentration of hydroxide ions. Therefore LiOH is an Arrhenius base. Group 1 and Group 2 hydroxides are the common Arrhenius bases.

While acetic acid is a weak acid which increases the concentration of H+ ions & it is an Arrhenius acid.

NaBr is a salt.

CH3OH is an organic compound which does not dissociates in aqueous solution as it contains covalent bonds.
