THINK CAREFULLY!

a. 8.46
b 6.71
c. 10.98
d. 5.54​

Answer 1

Answer:B

Step-by-step explanation:

Answer 2

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.
