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:How much of the body's inorganic salts account for the weight of the body?: The inorganic salts in the human body account for about 5%

Q:A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions: its not a so try b or c those 2 are the most likely to be the right answers

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:What is the most important inorganic salt in plant growth?: The inorganic salts required by plants are nitrogen, phosphorus and potassium containing inorganic salts, and if any lack of plants will affect the normal growth of plants, nitrogen is a component of many important organic compounds in the body, such as protein, nucleic acid, chlorophyll , Enzymes, vitamins, alkaloids and some hormones contain nitrogen. Nitrogen is also the basis of genetic material in all organisms, the most important protein, it is often in the center of metabolic activity.Now is to limit the growth of plants and the formation of the primary Factor. It also has a significant effect on improving the quality of the product.K2 is dissolved in the plant juice, and its main function is related to the metabolism of the plant.The content of phosphorus in the plant is second only to nitrogen and potassium, Phosphorus plays an important role in plant nutrition. Almost all important organic compounds in plants contain phosphorus. Phosphorus is involved in photosynthesis, respiration, energy storage and delivery, cell division, cell enlargement and other processes in plants.

Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?: The main physiological function of protein: 1. constitute the body, repair organization. (The body's muscles, blood, skin, hair, etc. are not the same as the protein is not formed.) 2. Regulate the physiological function. (The body of enzymes, hormones, antibodies, etc., are also directly or indirectly from the protein.) 3. Supply of energy. (Per gram of protein in the body of oxidation can release 4 kcal of heat for metabolic purposes.)

Q:My inorganic diet seems to be working but I am getting tired of the taste of rock salt. Should I continue?: Its all a matter of self-preservation.

Q:What foods contain inorganic salts?: Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.

Q:What is inorganic salt? Lemon flavor, citric acid, is it an inorganic salt?: Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain the normal level of citric acid is an important organic acid, also known as citric acid, no ...

Q:My body fat rate 14.6 normal body fat percentage 31.2 is more than the normal value I do not know the difference between the two please God answer ah Thank you very grateful and then those elements of my lack of God is the situation ah I love meat is not a vegetarian! And I super love to eat eggs! And my super love to drink water!: I am also a little lower inorganic salt so point, the coach said that usually drink some salt. Protein and water are low can only explain a problem, have a good fat under the conversion.

Q:I need help with this: anything which contain carbon is organic. so enzyme is the odd one out.
