Question: The use of monolithic columns and continuous beds in liquid chromatography is already very common. To this end: 
 Options:  <1> Microporous membranes are used so that the interaction between a solute and the matrix takes place in the final part of the pore. <2> A separation medium is introduced with a greater degree of continuity than the stationary particle phase so that the mobile phase is forced to traverse the large pores of the medium, improving mass transport. <3> Monodisperse particles are used as a stationary phase in order to improve mass transfer. <4> Flexible organic gels are used from microporous polymers in order to decrease the flow rates. <5> Columns filled with small particles of polymerized silica are used.

Question: A potentiometric titration is always done at i = 0: 
 Options:  <1> Yes, because that is where the Nernst equation is fulfilled. <2> Yes, because it is an instrumental requirement. <3> No, because there are potentiometric titrations at constant i. <4> No, because potentiometric titrations are never made at i = 0. <5> Yes, as long as an indicator electrode and a reference electrode are used.
