Question
What is the pH of a solution that contains hydroxide ions at a concentration of 6.3 x 10-4 M ?
Question 13
Select one:
- a. 3.2
- b. 6.3
- c. 1.6
- d. 10.8
Solution
To find the pH of a solution, we first need to find the pOH, since we are given the concentration of hydroxide ions (OH-). The pOH is found using the formula:
pOH = -log[OH-]
Substituting the given concentration into the formula:
pOH = -log(6.3 x 10^-4)
This gives a pOH of approximately 3.2.
The pH and pOH of a solution are related by the equation:
pH + pOH = 14
So, to find the pH, we subtract the pOH from 14:
pH = 14 - pOH pH = 14 - 3.2 pH = 10.8
So, the pH of the solution is approximately 10.8. Therefore, the correct answer is d. 10.8.
