We moved on to different article that also tries to explain why the liked charged macroions/polyelectrolytes (DNA in particular) will want to stay attached together,in a condensed form ,when counterions are added to a solution in which they are in. We also learned ,from kurt, about the role that enthalpy and entropy play in this procedure. We learned about why the system as a whole chooses to preserve its entropy at the expense of its enthalpy by using its highest mutli-valent ion in the bonding process. I have learned a lot in just two days. It is going to be a great summer!!
