H3O+ is nothing but the hydronium ion that is cation of the hydrogen atom.
The given concentration of H+ ion is 0.0001M
That is equal to 10^-4M
As we know, pH= -log[H+]
so putting values pH =-log[10^-4]
=-[-4]
=4
So pH is 4.
Practice more sums from the chapter Chemical Equilibrium of physical chemistry as this is a type of question that is frequently asked in entrance exams.
Best wishes. Thank you.
