Answer:

The correct answer is option d.

Step-by-step explanation:

Concentration of hydrogen ions =
[H^+}=3.45* 10^(-9) M

The pH of the solution is given by :

$pH=-\log[H^+]$

$pH=-\log[3.45* 10^(-19)]=8.46$

The relation between the pH and pOH is given by :

pH + pOH = 14

pOH = 14 - pH

pOH=14-8.46=5.54

The pOH of the substance is 5.54.
