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:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?: water and salt aren't foods. There is no caloric value in them, so they cannot be foods. We live on earth. All foods have an organic origin.

Q:in the ocean: Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.

Q:The power of the water and inorganic salts in the plant is derived from the action of the plant: Capillary siphon, as well as leaf water transpiration power.

Q:What fruit contains more minerals?: Watermelon fruit contains 90% or so, so there are "watermelon," said watermelon contains a variety of nutrients and chemical substances. Watermelon pulp contains protein, sugar, crude fiber, potassium, phosphorus, calcium, iron, sodium, magnesium Chlorine, niacin, vitamin A, vitamin B1 and vitamin B2 in the watermelon juice also contains citrulline, alanine and glutamic acid and other amino acids, malic acid and other organic acids, pectin and a small amount of glycosides, and Medlar, cinnamon and other alkaloids and so on.

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:For science I have to find out what salts are used for but when i search a salt like lithium sulphate it always comes up with &quot;would you like to buy&quot; could you please tell me what these salts are used for*lithium sulphate*zinc nitrate*sodium phosphate: 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:Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.: The roots of plants are usually divided into roots, roots, roots, roots (roots, roots and roots) for the absorption of roots, the absorption of roots from the soil to absorb water and inorganic salts, through the transport organization to reach the xylem catheter, through the catheter To the various organs of the plant (including leaves). The effect of the absorption of roots through the semipermeable membrane of the role of penetration, that is, the concentration inside and outside the cell membrane is poor. Transpiration can provide transport power for the transport tissue, like a pump to the water and water carrying inorganic salts to the top of the plant. Or first through the root absorption, and then through to the transport.

Q:The application of various inorganic salts in the human body?: Silicon in the water was partial silicic acid form absorbed by the body, mainly distributed in human skin and connective tissue, in the process of skeleton has a physiological role in promoting the development of bone development. Silicon is also involved in the metabolism of polysaccharides, is to form some glucose The main component of the aminopolysaccharide carboxylic acid.

Q:citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!: as it has no other sources of nutrition, only citrate metabolizers will be able to grow and thrive on this medium. If your organism grows, you know it is a citrate metabolizer which helps to identify the bacteria.

Q:Which foods contain calcium-containing inorganic salts: Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat
