pH=-log[H+]
PH=-log 1.7x10E-9
pH=8.77

SINCE THEY ASK YOU FOR pOH just use the formula.

pH+pOH=14
pOH=14-pH
pOH=14-8.77
pOh=5.23

Answer : The correct option is, (B) 5.23

Explanation :

pH : It is defined as the negative logarithm of hydrogen ion concentration.

Mathematically, it is represented as :

[tex]pH=-\log [H^+][/tex]

First we have to calculate the pH.

[tex]pH=-\log [H^+][/tex]

[tex]pH=-\log (1.7\times 10^{-9})[/tex]

[tex]pH=8.77[/tex]

Now we have to calculate the pOH.

[tex]pH+pOH=14\\\\pOH=14-pH\\\\pOH=14-8.77=5.23[/tex]

Therefore, the pOH of the solution is, 5.23
