A certain complex of metal M is formulated as MCl3 ∙ 3 H2O . The coordination number of the complex is not known but is expected to be 4 or 6.
(a) Would conductivity measurements
provide information about the coordination number?
(b) In using conductivity measurements to test which ligands are bound to the metal ion, what assumption is made about the rate at which ligands enter or leave the coordination sphere of the metal?
(c) Suppose you experimentally determine that this complex exists in aqueous solution as a single species. Suggest
a likely coordination number and the number and type of each ligand.
