All arenius acid are also bronsted lowry but all arrhenius base are not bronsted lowry base.

False

Explanation:

All Arrhenius acids and bases are also Bronsted-Lowry acids and bases.

An Arrhenius base is a compound that dissociates to form hydroxide ions in water.

NaOH (s) → Na^ + (aq) + OH^ - (aq)

A Bronsted-Lowry base is a proton acceptor.

NaOH is a Bronsted-Lowry base because the hydroxide on can accept a proton from HCl to form water.

Thus, all Arrhenius bases are Bronsted-Lowry bases.
