Chapter 18, Problem 18.7P

Interpretation Introduction

Interpretation:

The Arrhenius base from the given ${\text{H}}_{\text{3}}{\text{AsO}}_{\text{4}}{\text{, Ba(OH)}}_{\text{2}}\text{, HClO, KOH}$ 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.
