Chapter 11.5, Problem 11.36QAP

Interpretation Introduction

Interpretation:

“If a base is added to pure water, why does the [ $H_3{O}^{+}$] decreases.” should be explained

Concept introduction:

► Acid: According to Arrhenius; a substance that increases the concentration of ${\text{H}}^{\text{+}}$(hydrogen ion) in water is called acid. For example:

$\text{HCl}\stackrel{{\text{H}}_{\text{2}}\text{O}}{\to }{\text{H}}^{\text{+}}{\text{ + Cl}}^{-}$

► Base: According to Arrhenius; a substance that increases the concentration of $O{H}^{-}$ (hydroxide ion) in water are called base. For example:

$\text{NaOH}\stackrel{{\text{H}}_{\text{2}}\text{O}}{\to }{\text{Na}}^{\text{+}}{\text{ + OH}}^{-}$
