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

Q:Effect of Inorganic Salts on Viscosity
possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
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:Can inorganic salts be tested by LC / MS?
LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
Q:Relation between salt concentration and amount of drops of saltwater on a penny?
The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:How to add inorganic salts
Helicobacter pylori can cause a variety of stomach problems, including gastritis, gastric ulcer, duodenal ulcer, non-ulcerative indigestion, gastric cancer. Therefore, the eradication of Helicobacter pylori has become an important measure for the treatment of modern gastrointestinal diseases. To identify patients with Helicobacter pylori infection, the clinical need for a high sensitivity, specificity, fast, simple, safe, inexpensive Hp diagnostic method, that is, carbon 14 breath test. The examination and painless, noninvasive, fast and simple, no cross the advantages of infection, experts at home and abroad have been recommended for the diagnosis of Hp gold standard, has been widely used in clinical practice.
Q:What is the physiological function of inorganic calcium
Cells and organisms of the important components
Q:Does the plant absorb some of the inorganic salt?
Plants absorb moisture through the infiltration of root cells to absorb moisture, the process is essentially a free diffusion of water, neither the carrier nor the need for energy;
Q:Several inorganic salts are lacking in symptoms and food sources
Phosphorus-containing inorganic salts of food sources: seafood and so on
