Dilute Aqueous Solutions

The methods of polarographic analysis have been applied to the study of dilute aqueous solutions of various divalent transition metal cations coordinated to p-toluenesulfonyl glycine. Metal cations used were cadmium (II), copper (II), lead (II), mercury (II), manganese (II) and zinc (II). Six new and previously unreported compounds were prepared and studied polarographically, and their dissociation constants and coordination numbers are herein reported. Free energies of formations are also given for several of the complexes. In general, these data agree with similar data in the literature for the complexes of glycine itself.
