The heat content of the binary As-Zn and As-Cd systems were determined by a drop calorimeter in the concentration range from xAs = 0.04 to 0.48 in the As-Zn system and in the As-Cd system from xAs = 0.10 to 0.40. The temperature range for the zinc system was from 800 K to 1450 and for the cadmium system from 750 K to 1250 K. The method of the thermodynamic analysis was applied to derive the other thermodynamic properties from the heat content measurements of both binary systems. In the As-Zn system the heat of mixing has a peaked minimum at approximately xAs = 0.43 and the parabolic curve of the entropy of mixing exhibit a depression at the same composition. These strongly temperature dependent anomalies are explained by the existence of some sort of chemical short range order in the liquid. With increasing temperature these associates begin to dissociate.
