Recall; pH + pOH = 14
In this case [OH-] =0.100 m
therefore;
pOH = -LOG[OH-]
= - Log (0.100)
= 1.00
Therefore; the pOH is 1.00
And since, pH +pOH = 14
Then pH = 14-pOH
= 14 -1
= 13
Thus the pH is 13.00
I am so sorry I do not know but I need to answer a question in order to ask one I hope u pass:))

The PH of water is 7 because it contains an equal amount of h and oh- ions.
