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: and what are the kinds of organic compounds?..pls. help me abt. this..thanks!..(^_^)
- Any carbon-containing compound is considered organic with the exception of carbonates, bicarbonates, carbon dioxide and carbon monoxide.
- Q: What foods contain inorganic salts?
- Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice
- 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.
- Q: Do inorganic mercury salts bioaccumulate?
- Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ
- Q: General identification method of inorganic salts
- Take the test solution, add thiocyanate solution solution, that is blood red. Fe3 + + NH4SCN → Fe (SCN) 2 + (blood red) Take the test solution, plus potassium ferrocyanide test solution, that is, white precipitate, separation, precipitation in dilute hydrochloric acid insoluble. 3Zn2 ++ 2K4 [Fe (CN) 6] → K2Zn [Fe (CN) 6] 2 ↓ (white) + 6K +
- Q: What is the use of inorganic salts and organic salts?
- The organics are compounds containing carbon, and the inorganic salts are salts containing no carbon. For example, we usually eat sugar is organic matter, salt is inorganic salt.
- Q: The inorganic salt is composed of?
- Inorganic salts are the general term for various inorganic salts. They are composed of inorganic acid radicals and metal cations or ammonium salts, mainly salts of organic acid salts, such as sodium chloride, potassium chloride and so on.
- Q: What is the risk of low inorganic salt?
- Iodine content in the human body is much lower than 1/10000 is a trace element. Function iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases endemic goiter and local minor illnesses. Excessive symptoms iodine goiter, iodine thyrotoxicosis. Supply Adult 150ug Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
- Q: Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
- Speaking of calcium, many people will think of white calcium or calcium carbonate powder, and even rich in calcium food, often people mention nothing more than white milk and tofu. In fact, in the high calcium content of food, in addition to shrimp, most of the other looks very black. Every 100 grams of food in the calcium content of more than 300 milligrams of food with kelp, seaweed, Nostoc, black fungus, black sesame and other black food, and some calcium content even up to thousands of milligrams, and milk calcium content is only in the middle level , About 100 grams per 100 grams of calcium. People's Liberation Army 305 Hospital Digestive Medicine chief physician Wang Zhijin said that these black food calcium content is indeed high, but the taste, taste less than some milk, some people, especially young people do not love to eat. And calcium can not just look at the content of calcium, the most important thing is the absorption of the human body, at this point, the advantages of milk is very obvious. The nutritional content of each food is not a single, milk in the same calcium supplement, but also provide a lot of protein, amino acids, fat and vitamins, and kelp is rich in iodine, black fungus has now become an effective prevention of heart Cerebrovascular disease one of the foods.
- Q: Inorganic salt through what way into the human body
- The role of inorganic salts on the human body 1. Inorganic salts in the human body is extremely uneven distribution. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue. 2. Inorganic salts are important for the structure of tissues and cells
