Chapter 16, Problem 5QAP

5. Given the general equation illustrating the reaction of the acid HA in water,

$\text{HA}\left(\text{aq}\right)+{\text{H}}_{\text{2}}\text{O}\left(\text{l}\right)\to \text{H}{3}_{}{\text{O}}^{+}\left(\text{aq}\right)+{\text{A}}^{-}\left(\text{aq}\right)$explain why water is considered a base in the Brønsted-Lowry model.
