(a)
Interpretation: The given solution with a concentration of hydrogen ion
Concept Introduction: For a given solution, pH can be calculated as follows:
Here,
(a)
Explanation of Solution
The given concentration of hydroxide ion is
Substitute the values,
Since the pH of the solution is more than 7, thus, the solution is basic in nature.
(b)
Interpretation: The given solution with a concentration of hydroxide ion
Concept Introduction: For a given solution, pH can be calculated as follows:
Here,
Similarly, pOH can be calculated as follows:
Here,
The relation between pH and pOH of the solution is represented as follows:
(b)
Explanation of Solution
The given concentration of hydroxide ion is
Substitute the values,
Now, pH is calculated from pOH as follows:
Substitute the value,
Since the pH of the solution is more than 7, the solution will be basic in nature.
(c)
Interpretation: The given solution with a concentration of hydrogen ion
Concept Introduction: For a given solution, pH can be calculated as follows:
Here,
(c)
Explanation of Solution
The given concentration of hydrogen ion is
Substitute the values,
Since the pH of the solution is less than 7, thus, the solution is acidic in nature.
(d)
Interpretation: The given solution with concentration of hydroxide ion
Concept Introduction: For a given solution, pH can be calculated as follows:
Here,
Similarly, pOH can be calculated as follows:
Here,
The relation between pH and pOH of the solution is represented as follows:
(d)
Explanation of Solution
The given concentration of hydroxide ion is
Substitute the values,
Now, pH is calculated from pOH as follows:
Substitute the value,
Since the pH of the solution is equal to 7, the solution will be neutral in nature.
