The Property of Sodium Sulfite

Posted in General | 09:24

Everybody knows that Sodium Sulfite can be widely applied many ways. For example, it is used in the production of sodium thiosulfate. sodium sulfite is also applied in froth flotation of ores, oil recovery, food preservatives, making dyes. Sodium sulfite(Na2SO3) is decomposed by even weak acids, giving up sulfur dioxide gas. Solutions exposed to air are eventually oxidized to sodium sulfate. If sodium sulfite is allowed to crystallize from aqueous solution at room temperature or below, it does so as a heptahydrate. The heptahydrate crystals effloresce in warm dry air. Heptahydrate crystals also oxidize in air to form the sulfate. The anhydrous form is much more stable against oxidation by air. Yuanye Chemical Co., Ltd. was founded in 1954, as a professional manufacturer of sodium thiosulphate, sodium metabisulfite, sodium bisulphate, sodium sulfite, sodium bicarbonateand with years of exportation experience, we are fully knowledgeable of the product property and can handle the product delivery.

Usage of Potassium metavanadate

Posted in General | 10:04

Potassium metavanadate is the most common laboratory vanadate reagent, along with Ammonium metavanadate. But it is also accompanied by danger. Potassium metavanadate is a colorless to pale green colored crystalline solid that it may be toxic by ingestion if you contact will irritate skin, eyes and mucous membranes. It is used as raw material for catalysts, as well as raw material for agriculture and pigments. It is well-known that Potassium metavanadate is also used to make dyes, inks and laundry compounds. Benren Alloy Co.Ltd was founded in 1988. With years' development, it has become a newly high tech enterprise which involves in the production of Vanadium Pentoxide V2O5,Ammonium Dimolybdate,Molybdenum Bar,Tungsten Bar widely used in the field of steel, chemical, electronics, ceramics and so on. Armed with the latest production arts of ferrovanadium, Benren Alloy also obtain many breakthroughs in the creation of technology, the management of human resources and the development of technologists.
