Chapter 14, Problem 3E

Interpretation Introduction

(a)

Interpretation:

The classification of an aqueous solution of stomach acid, $\text{pH}\text{1}\text{.5}$ as strongly acidic, weakly acidic, neutral, weakly basic, or strongly basic is to be stated.

Concept introduction:

Acids are substances which lose a hydrogen ion, ${\text{H}}^{\text{+}}$, in water and are sour in taste. Strong acids have $\text{pH}$ between $\left(\text{0-2}\right)$, weak acids have $\text{pH}$ between $\left(2-7\right)$. A neutral solution has a $\text{pH}7$. Bases are the substances which loses a hydroxide ion, ${\text{OH}}^{-}$ ion in water. Strong bases have $\text{pH}\text{}$ between $\left(12-14\right)$, and weak bases have $\text{pH}$ between $\left(7-12\right)$.

(b)

Interpretation:

The classification of an aqueous solution of vinegar, $\text{pH}\text{3}\text{.2}$ as strongly acidic, weakly acidic, neutral, weakly basic, or strongly basic is to be stated.

Concept introduction:

Acids are substances which lose a hydrogen ion, ${\text{H}}^{\text{+}}$, in water and are sour in taste. Strong acids have $\text{pH}$ between $\left(\text{0-2}\right)$, weak acids have $\text{pH}$ between $\left(2-7\right)$. A neutral solution has a $\text{pH}7$.

Strong bases have $\text{pH}\text{}$ between $\left(12-14\right)$, and weak bases have $\text{pH}$ between $\left(7-12\right)$.

Interpretation Introduction

(c)

Interpretation:

The classification of an aqueous solution of distilled water, $\text{pH}\text{7}\text{.0}$ as strongly acidic, weakly acidic, neutral, weakly basic, or strongly basic is to be stated.

Concept introduction:

Acids are substances which lose a hydrogen ion, ${\text{H}}^{\text{+}}$, in water and are sour in taste. Strong acids have $\text{pH}$ between $\left(\text{0-2}\right)$, weak acids have $\text{pH}$ between $\left(2-7\right)$. A neutral solution has a $\text{pH}7$.
