A certain complex of metal M is formulated as MCl3 * 3H2O. 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 i made about the rate at which ligands enter or leave the coordination sphere of the 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.
however, it takes more CaCl2 to form a White solid in one of the solutions than the other. Using the data from your experiment to help, explain what is happening when CaCl2 is reacted with the NaHCO3 (aq) or Na2CO3 (aq) solutions.
