Which of these solutions is the most basic?

[H+] = 1 x 10^–2 M
[OH–] = 1 x 10^–4 M
[H+] = 1 x 10^–11 M
[OH–] = 1 x 10^–13M
I think it is C - please explain - I'm guessing and don't really understand..Thanks

THe highest pH is the most basic.

14-pOH=pH

pOH=-log[OH-]
pH=-log[H+]

Use the formulas and see if you are correct, but I believe that you are.
Thank you...
Yes, C is correct.
[H+]= 1 x 10^–11 M
