Concept Introduction:
The acidity or alkalinity of a solution is expressed by determining pH of the solution. pH of a solution is defined as negative logarithm of the concentration of
pOH of a solution is defined as negative logarithm of the concentration of hydroxyl ion (
Both pH and pOH are related to each other by this following equation-
At 25 °C the value of
Where,
(a)

Answer to Problem 22A
The concentration of
Explanation of Solution
Using following equation to calculate the concentration of
Since,
[OH-] = 2.32 × 10-4 M
Or,
Here, concentration of H+ ion is lower than 10-7. So the solution is basic.

(b)

Answer to Problem 22A
The concentration of H+ ion is1.11 × 10-5 M and the solution is acidic.
Explanation of Solution
Using following equation to calculate the concentration of H+ ion,
Data given: [OH-] = 8.99 × 10-10 M
Here, concentration of H+ ion is higher than 10-7. So the solution is acidic.
(c)
Interpretation:
The concentration of H+ ion has to be calculated. Whether the solution is acidic or basic is to be indicated.

Answer to Problem 22A
The concentration of H+ ion is 2.30 × 10-9 M and the solution is basic.
Explanation of Solution
Using following equation to calculate the concentration of
Here,
[OH-] = 4.34 × 10-6 M
Thus,
Here, concentration of H+ ion is lower than 10-7. So the solution is basic.
