Chapter 14, Problem 5QRT

(a)

Interpretation Introduction

Interpretation:

Acid, base and their conjugate partners has to be designated in the given equation.

    ${\text{HNO}}_{\text{3}}(aq)+{\text{H}}_{\text{2}}\text{O}(l)\to {\text{H}}_{\text{3}}{\text{O}}^{+}(aq)+{\text{NO}}_{\text{3}}{}^{-}(aq)$

Concept Introduction:

Conjugate acid-base are simply a pair of molecules or ions that are related to each other by loss or gain of a single proton.  Difference between conjugate acid-base pair is ${\text{H}}^{\text{+}}$ ion.  For a Brønsted-Lowry acid, the conjugate base has fewer ${\text{H}}^{\text{+}}$ and for Brønsted-Lowry base, the conjugate acid has more ${\text{H}}^{\text{+}}$.
