    7. (a) 0.05 M NaOH
    NaOH(aq) = Na+ (aq) + OH- (aq)
    t = 0 0.05 M 0 0
    t = t 0 0.05 M 0.05M
    [OH-] = 0.05 M
    pOH = -log[OH-]
    pOH = -log(0.05)
    = - log(5 x10-2)
    = 2-log5
    = 1.30
    pkw = pOH + pH
    pKw =14
    pH = pKw - pOH
    = 14 - 1.30
    = 10.70

    (b) 0.14 M ...

    Solution Summary

    Analytical chemistry calculation relationships are discussed. The relationship between pH, pOH and pKw are determined.
