You just caught a saboteur (from the competing laboratory across campus) dumping a toxic agent (Eco-Killer) into your laboratory model aquatic ecosystem tank.  Fortunately, you know that toxicant Eco-Killer is a weak acid, pKa  = 5.9.  Among your laboratory tools is a membrane purifier devise that can be used to circulate a purification fluid through a tube in the water of the ecology tank with only a membrane separating the two fluids.  What pH (at or between pH 5 and pH 9) would you use in the purifying fluid in order to rapidly remove Eco-Killer from the ecosystem tank into the tube holding the purifying fluid?  Assume the membrane purification system works just like mammalian cellular membranes and that the ecosystem tank ‘poisoned’ water has a pH = 6.5. You must show your work to receive full credit.
