What is the pOH value of a neutral solution?Question 9Select one:a.33b.1414c.77d.0

Break Down the Problem

1. Identify the characteristics of a neutral solution at standard temperature (25°C).
2. Understand the relationship between pH, pOH, and the ion product of water.

Relevant Concepts

1. In a neutral solution, the concentration of hydrogen ions $[H^+]$ is equal to the concentration of hydroxide ions $[OH^-]$.
2. At 25°C, the ion product of water $K_w$ is $1.0 \times 10^{-14}$.
3. The pH and pOH are related by the equation: $pH + pOH = 14$

Analysis and Detail

1. For a neutral solution: $[H^+] = [OH^-] = 1.0 \times 10^{-7} \, \text{M}$
2. Calculate the pH: $pH = -\log(1.0 \times 10^{-7}) = 7$
3. Using the relationship between pH and pOH: $pOH = 14 - pH$ $pOH = 14 - 7 = 7$

Verify and Summarize

We found that in a neutral solution, both the pH and pOH are equal to 7 at 25°C.

Final Answer

The pOH value of a neutral solution is 7.
