What is the function of Chinese medicine red powder? 4. Can mercury and sulfur treat scabies? 5. What is the function of "Red Ascending Dan"? What is mercuric oxide? Mercuric oxide (II), chemical formula HgO, commonly known as Sanxiandan, has two variants: red and yellow.
Mercury oxide is used to prepare other mercury compounds, and also used as catalyst, pigment, antibacterial agent and electrode material of mercury battery.
prepare
Red mercury oxide is prepared by heating mercury in oxygen or decomposing mercury nitrate at 350℃, and yellow mercury oxide is prepared by reacting a solution containing Hg2+ with hydroxide and precipitating. The particle sizes of the two are different, and the particles of red mercury oxide are smaller.
These two variants are orthogonal crystal systems with infinite chain structure in the same plane, and each mercury atom is almost linearly connected with two oxygen atoms around it, and coordinates with four oxygen atoms on adjacent chains at the same time.
∠O-Hg-O is 179∠Hg-O-Hg is 107.
Hexagonal mercury oxide can be obtained by the reaction of dilute solution of K2HgI4 with alkali. The structure is similar to orthogonal mercuric oxide, but the chains are not in the same plane, but wound in a spiral shape.
Reaction and use
Heating decomposes mercury oxide to produce oxygen and mercury vapor.
Although this method is rarely used to produce oxygen in the laboratory now, this reaction played a great role in the early development of modern chemistry.
1774, joseph priestley studied the decomposition reaction of mercury oxide, and called the generated gas (oxygen) "dephosphorization gas", which was later named "oxygen" by lavoisier (Greek meaning "acid").
Therefore, lavoisier further perfected his "oxidation theory".
2Hg 0→2Hg+O2
Mercury oxide is a weak base and can be used as an oxidant.
When chlorine is introduced into the newly made mercury oxide, chlorine monoxide can be obtained, and mercury oxide can be used to prepare this gas: 2cl2+2hgo → hgcl2 hgo+cl2o.
Mercury oxide reacts with hydrogen peroxide to produce mercury peroxide, which belongs to β -type orthorhombic system.
It can oxidize sulfur dioxide into sulfur trioxide, arsenic trioxide into arsenic pentoxide, and phosphorous acid in water into phosphoric acid.
Soluble in acid to form Hg(II) salt, limited soluble in alkali, the mechanism is not clear.
In addition, mercury oxide is also used to prepare other organic mercury compounds, which are used as pigments, catalysts, antibacterial agents and electrode materials of mercury batteries.

Can mercury and sulfur cure scabies? Putian is Chen Deliang's secret recipe to open the mountain gate. I think it should be useful, but the specific usage and dosage are not clear.
In traditional medicine in China, both mercury and sulfur can be used as medicine.

What is the function of "Red Ascending Dan"? In the Ming Dynasty, the China then family developed the formula of "salt-salt-salt-salt-salt-alum method" to refine powder coatings. By refining the mixture of alum, salt alum and mercury, high-purity mercury oxide-"Hongshengdan", also known as "Sanxiandan", is obtained, which is used to treat sores and carbuncles.
