  1. omg this is soooo easy...

    you have to -log it to get the pOH, you get 2

    then you subtract it from 14, because pH + pOH=14

    the answer is 12.00

    and just so you know if you're going from lets say pOH to the [OH], you would antilog the number 2 to get 0.010 M, same with pH, if you have pH and need the [H3O], you antilog it to get your answer. but lets say they're asking for the [H3O], and they give you the [OH], you have to get the pOH, then the pH, then antilog that to get the [H3O]... did they teach you the box trick how to remember this??? and did they teach you H3O is the same as H+?


  2. what does pH mean

  3. Ever heard of...

    www.google.com

    www.killerinfo.com

    www.ask.com

    search it out and stop trying to get others to do your homework. Thats not what the internet is for!

  4. i think 12.00 cause PH= -1* logarithm*[H+]

    As [OH-]=0.01so [H+]=0.000000000001

    As as result PH = -1*0.000000000001*log.=12.00=ANSWER

    always remember [OH-]*[H+]=0.00000000000001 so u can calculate both of them when u have only one of them.

  5. pH = -log[H+]

    [H+] x [OH-] = 10^-14

    [OH-] = 10.0^-2, so [H+] = 10.0^-12

    -log 10^-12 = 12, so your pH is 12.00

  6. someone is trying to cheat on a homework assignment lol idk

  7. 10

  8. one half of a third multiplied by 7.5 divided by 12.
