A) Basic nature increases on increasing pH
B) Basic nature decreases on increasing pH
C) Acidic nature increases on increasing pH
D) None of the above
Correct Answer: A
Solution :
\[pH=-\log [{{H}^{+}}]\] \[pOH=-\log [O{{H}^{-}}]\] and \[pH+pOH=14\] As \[pH\] of solution decreases it means concentration of \[{{H}^{+}}\] increases, hence acidic nature increases. On the other hand, if \[pH\] of solution increases concentration of \[O{{H}^{-}}\] also increases, so basic nature increases.
