Step 1:
I'll solve this step-by-step following the specified LaTeX formatting guidelines:

Step 2:
: Recall the relationship between pH and pOH

pH + pOH = 14
In aqueous solutions at standard temperature, pH and pOH are related by the following fundamental equation:

Step 3:
: Given information

We know that the pH of the solution is 7.

Step 4:
: Calculate pOH by rearranging the equation

pOH = 7
pOH = 14 - 7

Final Answer

This corresponds to a neutral solution, where the concentration of hydrogen ions [H⁺] equals the concentration of hydroxide ions [OH⁻]. Key Insights: - A pH of 7 indicates a neutral solution - At neutrality, pH = pOH = 7 - This relationship holds true for aqueous solutions at standard conditions (25°C)
