Answer:

d. 3.0

Explanation:

First we calculate the pOH of the solution, using the following formula:

pOH = -log[OH⁻]

pOH = -log[1x10⁻¹¹ M]

pOH = 11.0

Using the pOH we can calculate the pH of the solution, keeping in mind the relationship between pH and pOH:

pH = 14.0 - pOH

pH = 14.0 - 11.0

pH = 3.0

The answer is option d.
