Chapter 17, Problem 19CR
Interpretation Introduction

(a)

Interpretation:

The concentration of H+ ion in the given solution that contains 2.11×104MOH ion is to be calculated.

Concept Introduction:

The ionic product of water is the product of concentration of OH and H+ ion in water at a given temperature. The ionic product of water is represented as,

Kw=[H+][OH]

Where,

  • [OH] represents the concentration of OH ions in the solution.
  • [H+] represents the concentration of H+ ions in the solution.
  • Kw represents the ionic product of water.

Answer to Problem 19CR

The value of [H+] in the solution that contains 2.11×104MOH ion is 4.74×1011M.

Explanation of Solution

The concentration of OH in the solution is 2.11×104M.

The value of ionic product of water at 25°C is 1.00×1014M2.

The ionic product of water is represented as,

Kw=[H+][OH]

Where,

  • [OH] represents the concentration of OH ions in the solution.
  • [H+] represents the concentration of H+ ions in the solution.
  • Kw represents the ionic product of water.

Rearrange the above equation for the value of [H+].

[H+]=Kw[OH]

Substitute the value of [OH] and Kw in the above equation.

[H+]=1.00×1014M22.11×104M=4.74×1011M

Therefore, the concentration of H+ in the solution is 4.74×1011M.

Interpretation Introduction

(b)

Interpretation:

The pH of the given solution that contains 7.34×106MOH ion is to be calculated.

Concept Introduction:

The term pH referred to the power of hydrogen. The pH of a solution is mathematically equal to the negative logarithm of concentration of H+ ion in solution. The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Answer to Problem 19CR

The pH of the solution is 8.87.

Explanation of Solution

The concentration of OH in the solution is 7.34×106M.

The value of ionic product of water at 25°C is 1.00×1014M2.

The ionic product of water is represented as,

Kw=[H+][OH]

Where,

  • [OH] represents the concentration of OH ions in the solution.
  • [H+] represents the concentration of H+ ions in the solution.
  • Kw represents the ionic product of water.

Rearrange the above equation for the value of [H+].

[H+]=Kw[OH]

Substitute the value of [OH] and Kw in the above equation.

[H+]=1.00×1014M27.34×106M=1.36×109M

Therefore, the concentration of H+ in the solution is 1.36×109M.

The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Substitute the value of [H+] ions in the above equation.

pH=log(1.36×109M)=8.87

Therefore, the pH of the solution is 8.87.

Interpretation Introduction

(c)

Interpretation:

The pOH of the given solution that contains 9.81×108MOH ion is to be calculated.

Concept Introduction:

The pOH of a solution is used to measure the alkalinity of the solution. The pOH of a solution is mathematically equal to the negative logarithm of concentration of OH ion in solution. The pOH of a solution is represented as,

pOH=log[OH]

Where,

  • [OH] represents the concentration of OH ions in the solution.

Answer to Problem 19CR

The pOH of the given solution that contains 9.81×108MOH ion is 7.01.

Explanation of Solution

The concentration of OH ions in the solution is 9.81×108M.

The pOH of a solution is represented as,

pOH=log[OH]

Where,

  • [OH] represents the concentration of OH ions in the solution.

Substitute the value of [OH] in the above equation.

pOH=log(9.81×108M)=7.01

Therefore, the value of pOH is 7.01.

Interpretation Introduction

(d)

Interpretation:

Answer to Problem 19CR

Explanation of Solution

The pH of the solution is 9.32.

The relation between pH and pOH of a solution is given as,

pOH=14pH

Substitute the value of pH in the above equation.

pOH=149.32=4.68

Therefore, the pOH of the solution is 4.68.

Interpretation Introduction

(e)

Interpretation:

The pH of the given solution that contains 5.87×1011MH+ ion is to be calculated.

Concept Introduction:

The term pH referred to the power of hydrogen. The pH of a solution is mathematically equal to the negative logarithm of concentration of H+ ion in solution. The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Answer to Problem 19CR

The pH of the given solution that contains 5.87×1011MH+ ion is 10.23.

Explanation of Solution

The concentration of H+ ions in the solution is 5.87×1011M.

The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Substitute the value of [H+] ions in the above equation.

pH=log(5.87×1011M)=10.23

Therefore, the pH of the solution is 10.23.

Interpretation Introduction

(f)

Interpretation:

The concentration of H+ ions in the given solution that has 5.83pH is to be calculated.

Concept Introduction:

The term pH referred to the power of hydrogen. The pH of a solution is mathematically equal to the negative logarithm of concentration of H+ ion in solution. The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Expert Solution

Answer to Problem 19CR

The concentration of H+ ions in the given solution that has 5.83pH is 1.48×106M.

Explanation of Solution

The pH of the solution is 5.83.

The pH of a solution is represented as,

pH=log[H+]

Where,

  • [H+] represents the concentration of H+ ions in the solution.

Rearrange the above equation for the value of [H+].

[H+]=10pH

Substitute the value pH in the above equation.

[H+]=10(5.83)=1.48×106M

The concentration of H+ ions in the solution is 1.48×106M.
