Physical and Chemical Properties | Colorless orthorhombic crystal or white powder. Relative density 5.44(25 degrees C). Melting point 276 °c. Boiling point 302 °c. Soluble in hot water; Also soluble in ethanol, ether, acetic acid, pyridine and other organic solvents; Slightly soluble in cold water; Difficult to dissolve in carbon disulfide. The aqueous solution of mercuric chloride hardly dissociates and decomposes to produce mercurous chloride, hydrogen chloride and oxygen when exposed to light or air. Mercury chloride is decomposed with water, and its aqueous solution is acidic. In the case of sodium hydroxide to generate yellow mercury oxychloride precipitation, and ammonia to generate white amino mercury chloride precipitation, reaction with excess ammonia to generate complex [Hg(NH3)4]C12 extremely toxic! |

colorless crystals or white particles or powders. Melting point 277 °c; Boiling point 302 °c; D5.4. 19 The product was dissolved in 13.5 ml of water, 2.1 ml of boiling water, 3.8ml of ethanol, 1.6 ml of boiling ethanol, 22ml of ether, 200ml of benzene, 12mL of glycerol and 40ml of acetic acid. Soluble in methanol, ethyl acetate, acetone, slightly soluble in carbon disulfide, pyridine. There is a small amount of volatilization at room temperature. Mercury chloride, hydrogen chloride and oxygen are gradually decomposed when exposed to light or air. The aqueous solution of mercuric chloride is acidic. The reaction with the alkali metal can occur vigorously.
Mercury was pickled with nitric acid and filtered into a reactor, and reacted with dried chlorine gas to obtain mercury chloride gas, which was cooled to obtain mercury chloride.
for iron Capacity Analysis, arsenic, tin trace analysis, is a catalyst for organic synthesis, preservatives, disinfectants.
