**Question:**

What is the pH of a solution with a hydroxide ion concentration \([OH^-]\) of \(4.1 \times 10^{-4}\) M?

**Options:**

a. 7.00  
b. 2.39  
c. 11.6  
d. -11.6  
e. 10.6

**Explanation:**

To find the pH of the solution, you can first calculate the pOH using the formula:

\[ \text{pOH} = -\log [OH^-] \]

Then, use the relation between pH and pOH:

\[ \text{pH} + \text{pOH} = 14 \]

Calculate pOH:

\[ \text{pOH} = -\log (4.1 \times 10^{-4}) \]
\[ \text{pOH} \approx 3.39 \]

Now, calculate pH:

\[ \text{pH} = 14 - \text{pOH} \]
\[ \text{pH} \approx 14 - 3.39 = 10.61 \]

Therefore, the approximate pH is 10.6, which corresponds to option e.
