Mercury oxide mercury (II) (oxidation) is a kind of alkaline oxide, as inorganic substances, chemical formula for HgO, bright red or orange-red scaly crystalls or crystal powder, almost insoluble in water, insoluble in ethanol, 500 ℃ when the decomposition. Highly toxic, stimulating. Mercury oxide can be used for making other mercury compounds, and also used as a catalyst, pigment, antibacterial and mercury electrode material in the battery.
Bright red or orange-red scaly crystalls or crystal powder. When very fine powder of yellow, quality, no smell. But the color has nothing to do with particle size. Soluble in dilute hydrochloric acid, dilute nitric acid, alkali and alkali iodide cyanide solution, slowly dissolve in bromine
The lye, almost insoluble in water, insoluble in ethanol. Relative density 11.30. Toxic, median lethal dose (rats, through the mouth) 18 mg/kg. Stimulating. Action by light slowly becomes dark, there are poisonous! Heating when the temperature reached 500 ℃ oxide mercury will become elemental mercury, the decomposition of releasing oxygen (chemical equations for heat hgo = = 2 hg + O2 write). If the heating temperature below the decomposition temperature, color black, cold again after primary colors. Almost insoluble in water and ethanol, soluble in nitric acid and hydrochloric acid to form a high mercury salt.
