Answer: Option (B) is the correct answer.
Explanation:
The [tex][H^{+}][/tex] and [tex][OH^{-}][/tex] are interdependent on each other that is if the concentration of [tex]H^+[/tex] ions is high then the concentration of [tex]OH^-[/tex] ions is low and vice versa.
The pH of a substance can be calculated as follows.
pH = -log[tex][H^{+}][/tex]
This means when the concentration of [tex]H^+[/tex] ions is high then the pH of the solution or substance will be low.
It is also known that pH + pOH = 14, or pOH = 14 - pH.
Thus, we can conclude that when the pH is low then the pOH will be high and vice versa.
Therefore, option (B) is the correct answer that is a low [OH– ] and a high pOH.
