pH = 4 has (H^+) = 1E-4.
Then (H^+)(OH^-) = 1E-14
So if (H^+) = 1E-4, then (OH^-) must be 1E-10.
I am still lost? What is the answer 1, 2, 3 or 4?

If I told you that (H^+) = (OH^-) = 1E-7M in pure water, and that in this solution H^+ = 1E-4 and OH^- = 1E-10, then how would you classify (H^+) and (OH^-); i.e., are they relatively large or relatively small.
