Metallopolymers can be formed through the complexation of metal ions with the carboxylate groups of the polysaccharide illustrated below: The table below contains Log K values for selected metal ions, where K is the formation constant for the metal complex. Metal lon Pb2 Cd Cul Zn Log K 7.93-0.04 1.30+0.02 3.3610.06 0.71 0.03 Q 2(a) [5 Marks] With aid of a diagram, show the likely coordination sphere around the metal ions in the resulting metallopolymer. Q 2(b) [8 Marks] Calculate the free energy for the formation of a metallopolymer from each metal ion and identify which ion binds most strongly. Comment on the expected stability towards dissociation if each metallopolymer was individually precipitated and then resuspended in pure water. Q 2(c) [5 Marks] The metallopolymers are to be formed using 10 cm solutions of the polysaccharide and metal ion. If the concentration of the polysaccharide is 10 mM, determine the concentration of each metal ion needed to produce a metallopolymer in which one in every ten monomer units binds a metal cation. Q2(d) [15.33 Marks] With the aid of diagrams, discuss the expected differences in conductivity between the metal free polysaccharide and the metallopolymer formed using the most strongly binding metal ion.
