What is the pOH of a solution in which [H+] = 1 x 10-5 M?

Select one:
a. 9
b. 7
c. 10
d. 5

I feel like the answer is A.) can anyone confirm this or help me find the correct answer if my guess is wrong?

Here's my work:
[H+] *[OH-] = 10^-4
[OH-] = 10^-14/10^-5
[OH-] = 10^-9

Oh wait! It'd the pOH would be 5 right?

I just started acids but I agree with 9.

Okay, cool. Thanks again, Dan.

Np, and if your asking why, (h+) is an acidic property. So the pH would be 5, but pOH would just be 9.
