Mercury oxide (yellow)

参考价格：￥0.00
介绍 : Properties: orange-red flake crystal or crystalline powder. When the powder is very fine, it is yellow, heavy and odorless. 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 (chemical equation: 2HgO= heating =2Hg+O2↑).

If the heating temperature is lower than the decomposition temperature, the color turns black and returns to the primary color after cooling. Almost insoluble in water and ethanol, soluble in nitric and hydrochloric acid to form high mercury salts.
