    they cant prove its you, plenty of people get the same problem, and finding help is not cheating....

    -log(PH)=H
    -log(POH)=OH

    [OH][H]/[HA]=Ka

    Kw=1*10^-14

    Kw/Ka=Kb

    those are the equations you need, just solve it... I don't see the cheating in help and I'M A TEACHER.

    That's why you just shouldn't use your real name
