  1. 0.4M KOH = 0.4M OH^- and
    pOH = -log 0.4
    pOH = 0.398 and
    pH + pOH = pKw = 14
    pH = 13.6

    I am predicting acid-base equilibria using the Brondsted-Lowry predictions. I am asked to do "solid aluminum sulfate added to water". So I know there is an Al^2+ ion and a SO4^-2 ion, but does water dissociate into H30^+ and OH^-?
