1.General Description: Odorless white rhomboid prisms or a dense white powder. Density 6.77 g / cm3. Melting point 1170°F (632°C). Extremely toxic by ingestion. Very toxic by skin absorption and ingestion. A slow acting cumulative poison. Used as a rat poison, and an ant bait. Also used for analysis (testing for iodine in the presence of chlorine) and ozonometry. Not registered as a pesticide in the U.S.
2.Air & Water: Reactions Soluble in water.
3.Reactivity Profile : Thallium(i) sulfate has weak oxidizing and weak reducing powers. Redox reactions can however still occur.
4.Health Hazard :Rated as extremely toxic. The probable oral lethal dose in humans is 5 to 50 mg/kg, or between 7 drops and 1 teaspoon for a 150-pound person. The mean lethal dose in an adult is probably about 1 gm of Thallium(i) sulfate. Chronic exposure causes hair loss starting 10 days after exposure and complete baldness in about a month.
5.Fire Hazard :When heated to decomposition, Thallium(i) sulfate (2:1) emits very toxic fumes of thallium and sulfur oxide.
