is it the first one ?? Given a solution with a pOH of 13.6, what is the [OH-] of the solution? 13.6 M 2.51 x 10-14 M 0.4 M 3.98 x 10-1 M

    the relationship between [OH] and pOH is the same as the relationship between [H+] and pH\[pOH = -\log[OH^{-1}]\]and\[[OH^{-1}] = 10^{-pOH}\]

    so is it the first one cause they are the same? @JFraser

    if the concentration were the same thing as the pOH, there would be no need for both of them. They are not the same, the answer is not the first one

    get a calculator and plug it in, there's no need to guess

    \[10^{-13.6}\] should be a whole lot smaller than 0.4

    \(10^{-13.6}\) is incredibly small

    it is, but you need to know how to calculate logarithm and antilog functions to properly calculate pH, pOH, [H+] and [OH-] concenrations
