To determine the pOH Of solution we can use the pka value for the ionization constant of water at 25 degrees Celsius to solve this the relationship would be as follows.

PH + POH = 14

3.9 + x = 14

POH = 14 - 3.9 = 11 - 0.9 = 10.1

The POH would be 10.1.

Answer: pOH of the solution will be 10.1

Explanation:

pOH is defined as the negative logarithm of hydroxide ion concentration present in a solution. The equation used to represent pOH of the solution follows:

[tex]pOH=-\log[OH^-][/tex]

We are given:

pH of the solution = 3.9

To calculate the pOH os the solution, we use the following equation:

[tex]pH+pOH=14[/tex]

Putting values in above equation, we get:

[tex]3.9+pOH=14\\\\pOH=10.1[/tex]

Hence, pOH of the solution will be 10.1
