Dialysis dilution question

  1. May 10, 2004 #1
    I just can't quite get my head around this one.. and i suspect that the question or my head may have an error!

    Sounds a bit like dilution eh? The way i tried to work it out was

    1) The 10ml sample contained 0.03 moles of salt (n=CV)

    2) The water removes salt at 0.03 (concentration is 0.03M, in 1L of water) moles per water change

    3) The required level of ammonium sulfate in the internal solution is 10^-5 moles

    And I'm already ran into trouble... the external solution has already removed all the salt in the solution in one go! Somethign is wrong here... thanks for anyones help!
