By potentiometric titrations, in addition to the complexes known in literature, the anions [Hg(CN) 5 ] 3− and [Hg(CN) 6 ] 4− have been evaluated in concentrated solutions of KCN. Instability constants together with standard potentials and free energies were calculated.—After the complete formation of Hg(CN) 2 and addition of slight excess of HgCl 2 the electrode became incapacitated on account of the formation of Hg 2 Cl 2 .
