ACUTE TOXICITY OF ANTIMONY III TO SEVERAL SPECIES OF FRESHWATER ORGANISMS

Abstract

Antimony (.III) chloride is very soluble in water. The Merck Index (9th ed.) reports a solubility of 1 g SbC13 per 10.1 mL of water. This solution undergoes gradual hydrolysis to antimony oxychloride (Sb2Cl), which. is further hydrolyzed to antimony trioxide (Sb2o3)., both. of which are only slightly soluble in water. All of the above compounds are more soluble in solutions of high chloride ion content.
