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 $[OH^{-}] = 1.5\times 10^{-9}\ M$

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

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

$pOH = 8.82\\\\pH =?\\\\pH + pOH = 14\\\\pH + 8.82 = 14\\\\$

When collecting all the like terms:

$pH = 14 -8.82\\\\pH = 5.18$

Therefore, the solution of pH is 5.18.
