摘要：

Complexity constants for Hg(II)Cl- complexes have been determined at 25°C in 1 M NaClO4 ionic medium by potentiometric methods using redox Hg(II)Hg(I) half-cells. The values of the constants are. Hg2++Cl-⇆HgCl+,logk1=6·72±0·02 (1). Hg2++2Cl-⇆HgCl2,logk1k2=13·23±0·02 (2). HgCl2++Cl-⇆HgCl3-,logk3=1·00±0·01 (3). HgCl2++2Cl-⇆HgCl42-,logk3k4=1·97±0·025 (4). Hg2++HgCl2⇆2HgCl+,logK=0·22±0·02 (5) No evidence has been found for the formation of appreciable amounts of polynuclear species, such as Hg2Cl4, in solutions of HgCl2 up to 0·2 M. © 1968.
