If the pH of a solution is 3, what is the value of the pOH of the solution?

Explanation

To find the pOH of a solution when the pH is given, you can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between pH and pOH**: The relationship is given by the formula:
\[ \text{pH} + \text{pOH} = 14 \]

2. **Identify the given value**: In this case, the pH of the solution is provided as 3.

3. **Substitute the given pH into the formula**:
\[ \text{pOH} = 14 - \text{pH} \]
So, substituting the value of pH:
\[ \text{pOH} = 14 - 3 \]

4. **Perform the calculation**:
\[ \text{pOH} = 11 \]

5. **Conclusion**: The pOH of the solution is 11.

### Final Answer:
The value of pOH of the solution is **11**.
