Main use of Tin Tetrachloride

Submitted by admin on Wed, 11/07/2018 - 06:44

Tin Tetrachloride is a colorless, flowable liquid with gas molecules in a regular tetrahedral configuration. The bond length is Sn-Cl 228pm. The temperature of -33 ° C, the boiling point of 114.1 ° C. The density is 2.226 g/cm3. It is miscible with carbon tetrachloride, ethanol and benzene. It is easily soluble in water and soluble in most organic solvents such as gasoline, carbon disulfide and turpentine. Slowly add water to form a colloid of SnO2 and hexachlorostannic acid [H2[SnCl6]].

What is the manganese hydrogen phosphate

Submitted by admin on Mon, 11/05/2018 - 09:12

Manganese hydrogen phosphate is one of the natural ingredients of almost all foods and is widely used in food processing as an important food ingredient and functional additive. It is a salt of phosphoric acid and is an important substance in inorganic chemistry, biochemistry and biogeochemistry.

The naturally occurring Manganese hydrogen phosphate is a phosphate rock (including Manganese hydrogen phosphate) which is reacted with phosphate rock to form calcium dihydrogen phosphate and calcium sulfate which can be absorbed by plants to produce Manganese hydrogen phosphate.

Use of manganese hydrogen phosphate

Chemical fertilizer industry
Manganese hydrogen phosphate is generally used in detergents as a water softener, but in some areas manganese hydrogen phosphate cleaners are regulated because of the prosperous decay cycle of algae that affects phosphate discharge in watersheds.

There are generally three numbers of fertilizer grades: the first refers to the amount of nitrogen, the second refers to the amount of manganese hydrogen phosphate, and the third refers to alkaline water.

Lithium nitrate has a molecular formula of LiNO3 and a molecular weight of 68.95.

Lithium nitrate is colorless crystal and is hygroscopic. Heat to 600 ' C decomposition. Dissolved in about 2 parts of water, soluble in ethanol. The aqueous solution is neutral. The relative density is 2.38. The melting point is about 255 ' C. Strong oxidizing, rubbing or impacting with organic matter can cause burning or explosion. Irritating.

Physiological use of Bismuth

Submitted by admin on Fri, 10/26/2018 - 09:32

Bismuth exists in nature in the form of free metals and minerals. The metal Bismuth is obtained by calcination of minerals into Bismuth trioxide, followed by co-thermal reduction with carbon, and high-purity Bismuth can be obtained by fire refining and electrolytic refining.
