Calculate [OH-] in each/determine solution acidic, basic, neutral   [H3O + ] = 7.5 x 10-5M   [H3O + ] = 1.5 x 10-9M  [H3O + ] = 1.0 x 10-7M ?

    Since [H3O+] X [OH-] = 1.0X10^-14,

    [OH-] = 1.0X10^-14 / [H3O+]

    So, for each one just plug in [H3O+] and calculate [OH-].

    If [OH-] < 1X10^-7, the solution is acidic.

    If [OH-] > 1X10^-7, the solution is basic.

    If [OH-] = 1X10^-7, the solution is neutral.
