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 its the first one?

  • Chem -

    I would convert all to (OH^-), then the largest OH is the most basic. I don't think it's A.
    Or, you can do in your head pH.
    pH A = 2
    B = 10
    C = 11
    D = 1
    Most acid is?
    Most basic is?
