Chapter 16, Problem 16.15QP

(a)

Interpretation Introduction

Interpretation:

The hydrogen ion concentration of solution with $2.42$ of $pH$ has to be calculated.

Concept introduction:

• pH of a solution is the negative of the base $\text{-10}$ logarithm of the hydronium ion or hydrogen ion concentration.

  $\text{pH}\text{=}\text{-log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

• Concentration of hydronium ion $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]\text{=}{\text{10}}^{\text{-pH}}$
• For an acidic solution $\text{pH}\text{<7}$ and for a basic solution $\text{pH>}\text{7}$.

(b)

Interpretation Introduction

Interpretation:

The hydrogen ion concentration of solution with $11.21$ of $pH$ has to be calculated.

Concept introduction:

• pH of a solution is the negative of the base $\text{-10}$ logarithm of the hydronium or hydrogen ion concentration.

  $\text{pH}\text{=}\text{-log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

• Concentration of hydronium ion $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]\text{=}{\text{10}}^{\text{-pH}}$
• For an acidic solution $\text{pH}\text{<7}$ and for a basic solution $\text{pH>}\text{7}$.

(c)

Interpretation Introduction

Interpretation:

The hydrogen ion concentration of solution with $6.96$ of $pH$ has to be calculated..

Concept introduction:

• pH of a solution is the negative of the base $\text{-10}$ logarithm of the hydronium or hydrogen ion concentration.

  $\text{pH}\text{=}\text{-log}\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]$

• Concentration of hydronium ion $\left[{\text{H}}_{\text{3}}{\text{O}}^{\text{+}}\right]\text{=}{\text{10}}^{\text{-pH}}$
• For an acidic solution $\text{pH}\text{<7}$ and for a basic solution $\text{pH>}\text{7}$.

(d)

Interpretation Introduction

Interpretation:

The hydrogen ion concentration of solution with $15.00$ of $pH$ has to be calculated..

Concept introduction:
