The pOH of a solution is 11.34. calculate the pH and concentration of [OH-] and [H+].

I know pOH = 14 - pH, so...
11.34 = 14 - pH --> pH = 2.66

To find the [H+] and [OH-] concentration..

[H+] = 10^-pH, therefore the [H+] concentration is simply 10^-2.66 or .002, correct?

 and is the [OH-] just 11.34?

[Borek]

[H+] = 10^-pH

OK. But check significant figures in your answer.

and is the [OH-] just 11.34?

Compare with above.
