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: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:What does salt form when it dissolves?
- Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
- Q:Several kinds of inorganic salt food sources?
- Phosphorus-rich foods: fish, lean meat, untreated cereals, eggs, dried fruits, all kinds of seeds, etc. Almost all natural foods
- Q:How too much to eat too much inorganic salt
- Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
- Q:Is the conduction of excitement on neurons related to inorganic salts?
- Neurons, also known as nerve cells, constitute the basic unit of the nervous system structure and function.
- Q:what is the function of salts in DNA extraction?
- The role of the salt is to neutralize the charge of the DNA's sugar phosphate backbone. This makes the DNA less hydrophilic (less soluble in water). Ethanol has a lower dielectric constant than water so it's used to promote ionic bonds between the Na+ (from the salt) and the PO3- (from the DNA backbone) causing the DNA to precipitate, to extract DNA finally..
- Q:People lack the inorganic salt will be what disease
- iron deficiency will lead to iron deficiency anemia, immunity decreased.
- Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
- So we can say: all the minerals required by the human body are dependent on the supply of food.If the mineral and water pollutants to do comparison, then we can almost ignore the minerals in the water; , We would rather drink RO reverse osmosis water machine filtered out of the clean water, do not for that 0.01% of the minerals, and take our health joke.
- Q:Does the urine and urine contain inorganic salts? Anxious
- When the blood flows through the glomerular, in addition to blood cells and macromolecules of protein, the plasma part of the water, inorganic salts, glucose and urea and other substances, can be filtered through the glomeruli into the renal capsule, the formation of urine ; When the original urine through the renal tubular, which is useful for the human body substances, including most of the water, all the glucose and part of the inorganic salt, reabsorbed by the renal tubules, and into the capillaries outside the renal tube, To the blood; in the renal tubular reabsorption at the same time, renal tubular epithelial cells will produce substances (such as ammonia) secretion into the renal tubular bureaucratic, and the original urine of other waste, such as urea, part of the water and inorganic Salt, etc. from the renal tubular effusion, the formation of urine. Therefore, plasma, urine and urine are contained in the material is water, inorganic salts, urea.
- Q:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
- Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
