Chapter 14, Problem 4E

Interpretation Introduction

(a)

Interpretation:

The classification of an aqueous solution of battery acid, $\text{pH}\text{0}$ 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 $\text{pH}7$. 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 $\left(7-12\right)$.

Interpretation Introduction

(b)

Interpretation:

The classification of an aqueous solution of lime juice, $\text{pH}2.7$ 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 $\left(7-12\right)$.

Interpretation Introduction

(c)

Interpretation:

The classification of an aqueous solution of shampoo, $\text{pH}7.0$ 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 $\text{pH}7$.

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

Interpretation Introduction

(d)

Interpretation:

The classification of an aqueous solution of ammonia, $\text{pH}11.1$ as strongly acidic, weakly acidic, neutral, weakly basic, or strongly basic is to be stated.

Concept introduction:
