    You're cheating on an assignment due for the class Chemistry 1012, your chemistry professor will be notified.

    busted

    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
