Chapter 14.2, Problem 14.15QAP

Interpretation Introduction

Interpretation:

The balanced equation for the reaction of ammonium ion with water should be written.

Concept introduction:

► According to the Bronsted-Lowry acid-base definition, a Bronsted acid is a substance that donates proton, and after losing the proton it forms a conjugate base.

► In contrast, a Bronsted base is a substance that accepts a proton, and after gaining the proton it forms a conjugate acid.

Solution:

The balanced equation for the reaction of ammonium ion with water is:

${\text{NH}}_{\text{4}}{}^{\text{+}}{\text{(aq)+H}}_{\text{2}}\text{O(l)}\rightleftarrows {\text{NH}}_{\text{3}}{\text{(aq)+H}}_{\text{3}}{\text{O}}^{\text{+}}\text{(aq)}$
