4. Hydrargyri Chloridum Corrosivum. Corrosive Mercuric Chloride

Hydrargyri Chloridum Corrosivum. Corrosive Mercuric Chloride. HgCl2=270.54. Synonyms. - Corrosive Sublimate. Mercuric Bichloride. Corrosive Chloride of Mercury.

Source

Heat a mixture of Mercuric Sulphate, Sodium Chloride, and Manganese Dioxide. HgSo4+2NaCl+MnO2=HgCl2+ Na2So4+MnO2. The Corrosive Chloride sublimes and is condensed. The object of the Manganese Dioxide is to prevent the formation of Mercurous Chloride by setting free Chlorine, which will convert it into Mercuric Chloride.

Characters

Heavy, colorless rhombic crystals, or crystalline masses, having an acrid and persistent metallic taste. Solubility. - In 16 parts of water; in 3 parts of Alcohol.

Incompatibles

Alkalies and their carbonates, potassium iodide, lime water, tartar emetic, silver nitrate, lead acetate, albumin, soaps, vegetable preparations containing tannic acid, and in fact most substances. Dose, 1/60 to 1/10 gr.; .001 to .006 gm.

5. Hydrargyri Chloridum Mite. Mild Mercurous Chloride

Hydrargyri Chloridum Mite. Mild Mercurous Chloride. Hg2C12=470.34. Synonyms. - Calomel. Mild Chloride of Mercury. Subchloride of Mercury.

Source

Rub Mercury with Mercuric Sulphate to form Mercurous Sulphate, Hg2So4. Add Sodium Chloride, and then heat, the Calomel sublimes, Hg2So4+2NaC1=Hg2Cl2+Na2So4.

Characters

A white, impalpable powder without odor or taste.

Impurity

Corrosive Mercuric Chloride.

Dose, 1/2 to 10 gr.; .03 to .60 gm.
