Lithium iodide is a chemical substance with a molecular formula of LiI. White crystal, easy to deliquesce, see light or long-time color yellow; soluble in water, alcohol and acetone, ether; when melted, it is corrosive to glass and ceramic; heat to 73 ° C loses one molecule of crystal water, loses to 80 ° C Molecular crystallization of water. It can form a complex with a hydrocarbyl lithium and acts as a stabilizer.
Iron nitrate is colorless or lavender monoclinic crystal,
True Fe3+ ions and hexahydrate Fe3+ ions are lavender.
However, due to the usual pH conditions, hydrated Fe3+ ions are easily hydrolyzed.
Partially hydrolyzed products such as Fe(OH)2+ and other hydroxylates and oxyhydroxides, OH- and O2- as ligands, their coordination field effect is very strong.
The 3d energy level of Fe3+ is changed to yellow and yellowish brown, which also makes the solution yellow.
Nickel aminosulfonate is an excellent main salt for electroplating. Due to its low internal stress, fast plating speed, high solubility and no pollution, it has become a major electroplating main salt in the world. Has been widely used in electronics, automotive, aerospace, weapons, coinage, metallurgy, nickel mesh, radio, color aluminum alloy and other industries.

Merbromin is topical disinfectant for pharmaceutical and chemical products raw materials.
Potassium metaborate is a white loose powder or crystal with a molecular formula of K2B2O4.3H2O.
Relative density of Potassium metaborate 1.178 Solubility Soluble in water and slowly liberate hydrogen, slightly soluble in methanol and ethanol, almost insoluble in ether, benzene, tetrahydrofuran, methyl ether and other hydrocarbons.
Zinc chloride is one of the important products in the inorganic salt industry, and its application range is extremely wide. Zinc chloride is easily soluble in water and is the most soluble in solid salts (25 ° C, 432 g / 100 g) due to its solubility in water to form the acid H [ZnCl 2 (OH)]. Soluble in methanol, ethanol, glycerin, acetone, ether, insoluble in liquid ammonia. It is highly deliquescent and can absorb moisture from the air and deliquesce.
