(a)
Interpretation:
The pH of a solution with [H+] = 1.0x10-4 M needs to be calculated
Concept Introduction:
The acidity of a solution is expressed in terms of its pH which is essentially the measure of the hydrogen ion (H+) concentration of that solution. Mathematically,
If the pH is below 7 the solution is termed as acidic, if greater than 7 the solution is basic. A neutral solution will have a pH = 7
(a)
Answer to Problem 3E
pH = 4.0
Explanation of Solution
The given hydrogen ion concentration is as follows:
[H+] = 1.0x10-4 M
The pH of the solution is calculated as follows:
(b)
Interpretation:
The pH of a solution with [H+] = 1.0x10-12 M needs to be calculated.

(b)
Answer to Problem 3E
pH = 12.0
Explanation of Solution
The hydrogen ion concentration is given as follows:
[H+] = 1.0x10-12 M
The pH of the solution is calculated as follows:
(c)
Interpretation:
The pH of a solution with [OH-] = 1.0x10-8 M needs to be calculated
Concept Introduction:
The acidity of a solution is expressed in terms of its pH which is essentially the measure of the hydrogen ion (H+) concentration of that solution. Mathematically,
If the pH is below 7 the solution is termed as acidic, if greater than 7 the solution is basic. A neutral solution will have a pH = 7
The pH and pOH are related by the following equation:
Where:
(c)
Answer to Problem 3E
pH = 6.0
Explanation of Solution
The given hydroxide ion concentration is as follows:
[OH-] = 1.0x10-8 M
The value of pOH can be calculated as follows:
From calculated value of pOH, pH can be calculated as follows:
