Answer / sandip ankolia

Because of condivity of water is 1.0 x 10 -14
if water dissociation is H+ and OH-

H2O = 1.0 x 10-14
log (H2O) = log (1.0 x 10-14)
PH = 14

Answer / usha (gvk)

*** The equation for finding the pH of a solution is –log
([H+]). That is, the negative log of the molarity of the
hydrogen ions released by the compound in solution. Almost
no chemicals can release hydrogen ions with a molarity
greater than 1 or less than 10^-14. However, there are some
rare cases where the pH of a solution is not between 0 and
14. For example, 10 molarity hydrochloric acid (there are
ten moles of hydrochloric acid for every liter of water.),
has a pH of -1 (-log (10) =-1). But these are so rare in
occurrence.
