Lead stearate dibasic is a white powder, insoluble in water, soluble in hot ethanol, benzene and turpentine. It is heated and dissolved in an organic solvent and cooled to form a gel. It is decomposed into stearic acid and the corresponding salt in the presence of strong acid, and is hygroscopic. This product is toxic and susceptible to sulfide contamination. Do not dissolve in water, soluble in hot ethanol. Melting point 103-110 ° C

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.

The color of ferric nitrate solution?

Submitted by admin on Thu, 12/13/2018 - 07:25


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.

Use of zinc chloride

Submitted by admin on Mon, 12/10/2018 - 09:43

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.
