When heated it oxidizes to arsenous oxide, which has a garlic odour. It has steel-grey colour and is a very brittle, crystalline, semi-metallic solid, a metalloid solid. 1.97 and grey arsenic, metallic arsenic S.G. because these substances are very poisonous. It is used in dyes, pigments, medicines, lead shot alloy, glass-making, fireworks.Īrsenic and arsenic compounds are not use in school science experiments. The sodium chloride solution coagulates the control.ġ2.2.2 Reactions of arsenic and arsenic compoundsĪrsenic is widespread and abundant in the earth. Dilute 2 mL of the antimony sulfide solution with 2 mL of water to act as a control. The sodium chloride solution has no effect where the solution is protected by the starch.Ĥ. Add 2 mL of starch solution to 2 mL of antimony sulfide solution.
