Potenital Differnce between Salt Bridge and rxn

  1. Dec 2, 2008 #1
    1. The problem statement, all variables and given/known dataA 0.100 M solution of sodium palmitate (C15H31COONa) is separated from a 0.200
    M NaCl solution by a membrane barrier that is permeable to Na+ and Cl-, but not to palmitate

    I need to calculate the concentrations of the ions on both sides of the barrier once equilibrium is established. Along with the potential difference across the membrane due to the equilibrium established above.

    2. Relevant equations

    3. The attempt at a solution To find the concentration on each side, a comparison of Na, and Cl was made, and the each side was made equal to each other. This resulted in .15 Na, and .1 Cl for each side.
    To find the potential difference, equations from our data section were used, however these numbers did not seem right.
    Looking for any direction on how to get through the problem. Thanks!!

    What equations will describe equilbrium?
