    How do I calculate Pka if the weak base was diluted and made up to 100 ml while the acid was not?

    • @Leah4sciMCAT
      @Leah4sciMCAT  2 роки тому +1

      Diluting the base would decrease its concentration. Therefore, you would have to plug in a new concentration for A- in this equation for your diluted base and then, using the pH of the solution that you're given, solve for the pKa in a similar way.

      Does a graph of Pka Vs pH produce straight line graphs?

    Why can't I find one without someone using the Henderson equation, our professor doesn't want us to use it, because one doesn't fully understand what they're doing usually when using it, want the ice table long version

    • @Leah4sciMCAT
      @Leah4sciMCAT  7 років тому

      I'm sorry you're having trouble finding a video like that for your class, but this video is specifically designed to help students prepare for the MCAT. So I only gave the shortcut. You have to use a regular ICE table for the full version.

    LOL, a thousand moles of HCl will not fully dissociate in a liter of water. There are 55.5 moles of water in a liter. One thousand moles of HCl will absolutely not fully dissociate in one liter of water. Not enough water molecules to accept that many hydrons. If you are going to make chem vids, you better have it right. LOL
