    Answer:

    pOH = 11

    Explanation:

    The pH is an unit of concentration widely used in chemistry to find the quality of a solution.

    To solve this question we must, as first, find the [H+] using the pH:

    [H+] = 10^-pH

    [H+] = 10^-3

    Now, using kw:

    kw = 1.0×10-14 = [H+] [OH-]

    1.0×10-14 = [10^-3] [OH-]

    [OH-] = 1.0×10-11

    pOH = -log [OH-]

    pOH = 11
