Mercury oxide (red)

参考价格：￥
介绍 : Bright red or orange-red scaly crystals or crystalline powders. Heavy quality, no smell. But its color has nothing to do with its granularity. Soluble in dilute hydrochloric acid, dilute nitric acid, alkali cyanide and alkali iodide solution, slowly soluble in brominated lye, almost insoluble in water, insoluble in ethanol. The relative density is 11.30. Toxic, median lethal dose (rats, orally) 18mg/kg. It's stimulating.

Slowly turns dark by the action of light, and is highly toxic! When heated, mercury oxide becomes elemental mercury at 500 ° C, and oxygen is released when it decomposes (the chemical equation is 2HgO= plus)
