Question
pOH of H2O is 7.0 at 298 K. If water is heated at 350 K, which of the following statement should be true?
Options
A.pOH will decrease.
B.pOH will increase.
C.pOH will remain 7.0.
D.concentration of H+ ions will increase but that of OH- will decrease.
Solution
[OH-] = 
in pure water.
So as temperature increases Kw decreases ⇒ [OH-] decreases.
