Question
Which of these statements concerning pOH is correct?
pOH is based on the [OH-] in solution.
If [OH-] = 1.0 x 10-13, then the solution is basic.
pH = 8.0 is ten times more acidic than pH = 11.0.
If the pH > 7 then the solution is neutral.
Pure water has [OH-] < 1.0 x 10-7 M.

Explanation / Answer
Ans A. pOH is based on the [OH-] in solution.
As pH is the negative logarithm of hydrogen ion concentration in the solution likewise pOH is the negative logarithm of hydroxide ion concentration in the solution.
pOH less than 7 indicates the solution to be basic
