Question

What is the pH of a solution for which [OH−]
equals 8.26 × 10−10 M?

Answer 1

what's the relationship between the concentration of ions, pH, and pOH?

Answer 2

You don't have that information @jfraser

Answer 3

or you mean 14 = [ho] [pho]

Answer 4

that, and how do you turn the [H+] into pH? The relationships between them are always true, whether you're given them or not

Answer 5

the concentrations [H+] and [OH-] always multiply to the same constant, \(1.0*10^{-14}\) knowing that will get you the [H+], which you can turn into the pH
