Chapter 17, Problem 103SAE

Interpretation Introduction

Interpretation:

Whether the addition of ${\text{H}}_3{\text{O}}^{+}$, ${\text{KNO}}_3$, $\text{NaCl}$ or increase in $\text{pH}$ can result in the conversion of ${\text{NH}}_4^{+}$ to ${\text{NH}}_3$ should be identified.

Concept introduction:

When an acid donates ${\text{H}}^{+}$ ions, it forms a conjugate base, and when a base accepts ${\text{H}}^{+}$ ions, it forms the conjugate acid. In general, a strong base has a weak conjugate acid, and the weak base has a strong conjugate acid. For example ${\text{NH}}_4^{+}$ and ${\text{NH}}_3$ are the conjugate acid-base pair.
