At a certain temperature the value of pKw is 13.4 and the measured pH of solution is 7. The solution is

A.Acidic
B.Basic✓ Correct
C.Neutral
D.Unpredictable
Explanation

w pK = 13.4 that means, pH + pOH = 13.4 Thus, pH of pure water is 6.7. If  measured  pH  of  the  solution  is  7  then  solution  is basic.
