Answer
$B(aq) + H_2O(l) \lt -- \gt BH^+(aq) + OH^-(aq)$
Work Step by Step
Considering the Bronsted-Lowry theory, a base is a compound that is capable of receiving one proton $(H^+)$.
Therefore, when ionizing the water, the base (representend by "B"), takes a proton from the water molecule, producing "$BH^+$" and "$OH^-$".
