2.Main Features of Sodium Hydrosulfite

It is a versatile chemical that's used in the manufacture of a variety of products we all use every day, 

from photographic film to wine; from fine writing papers to leather goods; from colored fabrics to metal recovery.

While the applications for this chemical workhorse are as vast and as varied as the industries that use it, 

in most cases, sodium hydrosulfite performs one of the following three roles:

1) As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2) As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3) As cation source, hydrosulfite adds a cation, or sodium, to a product system

5.FAQ

1, how about your packing?

  My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag. 

 

2, how long time you can make the shipping?

  We can make the shipping within 5-10day after confirm the order. 

 

3, why you buy from me?

  We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q:what are the advantages and disadvantages of taking health care agents?
There will be no imbalance in the state, and those survey reports are often too exaggerated unbalanced side to emphasize the use of a balanced diet. You may want to talk about how the natural diet through the general way to add the advantages of inorganic salts, and the advantages and disadvantages of taking health care agents
Q:Where can I find a list of all inorganic salts?
That list is near endless. There are countless inorganic cations and organic groups that can combine with these ions. Pretty much every metallic element in the periodic table will form cations with bromide and chloride. Not sure about phosphate, but most metals will bind with it. Carbonate will be trickier, as some ions are too acidic and will decompose the carbonate (iron(III) is an example, and it will form the oxide instead, liberating CO2 in the process). Aside from simple elemental ions, there are also polyatomic cations (such as ammonium) and lots of complexes that will form compounds with these anions.
Q:How do inorganic salts enter the water?
Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.
Q:What are these salts used for please?
HI I'M PNT. LITHIUM SULFATE is a white inorganic salt with the formula Li2SO4. It is used to treat bipolar disorder. It is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature . This property is shared with few inorganic compounds, such as the lanthanoid sulfates. Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However they do suffer in this application because of their water solubility. ZINC NITRATE: Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate:Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3. Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its Relative Molecular Mass is 189. SODIUM PHOSPHATE: Sodium phosphate are forms of phosphorus, which is a naturally occurring substance that is important in every cell in the body. Sodium phosphate is used to treat constipation and to clean the bowel before surgery, x-rays, endoscopy, or other intestinal procedures. Sodium phosphate enemas are also used for general care after surgery and to help relieve impacted bowels. Sodium phosphate may also be used for other purposes not listed in this medication guide REGARDS, PNT.
Q:Why plasma osmotic pressure and protein, inorganic salt content
Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.
Q:Inorganic salt function
Although inorganic salts in the cell content is relatively small, but there are many important role.
Q:are acids, bases, salts and oxides belong to inorganic compound?
Organic compounds are anythng with carbon C in them. Acids or bases can be organic or inorganic depending on if they have a carbon atom in them. Salts result from a reaction of an acid and a base e.g. Sodium chloride NaCL results from a reaction of HCL and NaOH i.e. HCL + NaCL = NaCL + H20. A reaction involving an acid and a base results in a salt and water as shown above. So compounds are organic if they have carbon in them, including the oxides
Q:Is it possible to adjust the internal temperature of the carbohydrate in the vacuole
The plant has no internal environment.
Q:The effect of inorganic salt medium and the difference with enrichment medium
The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
