Answer:

The answer is "5.18 ".

Explanation:

It's a question of chemistry. Therefore, the following solution is provided:

We will first determine the solution's pOH. The following can possible:

The concentration of Hydroxide ion [tex][OH^{-}] = 1.5\times 10^{-9}\ M[/tex]

[tex]pOH =?\\\\pOH = -\log [OH^{-}]\\\\pOH = -\log 1.5\times 10^{-9}\\\\pOH = 8.82\\\\[/tex]

Furthermore, the pH of the solution shall be established. It was provided as follows:

[tex]pOH = 8.82\\\\pH =?\\\\pH + pOH = 14\\\\pH + 8.82 = 14\\\\[/tex]

When collecting all the like terms:

[tex]pH = 14 -8.82\\\\pH = 5.18[/tex]

Therefore, the solution of pH is 5.18.
