Chapter 18, Problem 18.5P

Interpretation Introduction

Interpretation:

The Arrhenius acid from the given ${\text{NaHSO}}_{\text{4}}{\text{, CH}}_{\text{4}}{\text{, NaH, H}}_{\text{3}}\text{N}$ has to be identified.

Concept introduction:

Arrhenius Acids and Bases:

Acid release hydrogen ion in water, base release hydroxide ions in water.

$\begin{array}{l}\text{HCl(aq) }\to {\text{H}}^{\text{+}}{\text{(aq) + Cl}}^{\text{-}}\text{(aq)}\mathrm{.................}\text{Acid}\\ \text{NaOH(aq) }\to {\text{Na}}^{\text{+}}{\text{(aq)+ OH}}^{\text{-}}\text{(aq)}\mathrm{...........}\text{Base}\end{array}$

An acid is a substance that produces hydronium ions, ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ when dissolved in water.
