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: Several kinds of inorganic salt food sources?: Milk containing calcium, spinach iron, kelp containing iodine, oysters containing zinc, carrots containing A, tomatoes containing C, mushrooms with B1, sun can get D

Q: How does inorganic salts maintain osmotic pressure and pH: Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.

Q: Nutritional characteristics of carbohydrates and inorganic salts in vegetables: Vitamins: Fresh vegetables and fruits are an important source of ascorbic acid, carotene, riboflavin and folic acid

Q: What is the inorganic salt: The main sources of various inorganic salts and the lack of the main performance (1) sodium sodium is the main ingredient of salt.China's nutrition society recommended adults over 18 years of age sodium intake of 2.2 grams per day, the elderly should take light food Sodium is commonly found in a variety of foods. The main sources of sodium are sodium, soy sauce, pickled foods, smoked foods, salty foods, etc. (2 Calcium is an important part of bone. Disease, osteoporosis, etc .. China Nutrition Society recommended adults aged 18-50 adult calcium intake of 800 mg per day; 50 years of age in the elderly 1000 mg.General calcium-rich foods are milk, yogurt, Oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily, etc. (3) magnesium is the necessary elements to maintain the structure and function of bone cells.Magnesium deficiency can lead to nervous tension, emotional instability, muscle tremor and so on. (4) Phosphorus is an important part of the composition of bones and teeth. (4) Phosphorus is an important component of bone and teeth. (4) Phosphorus is an important component of bone and teeth. Severe phosphorus deficiency can lead to anorexia, anemia, etc. China Nutrition Society recommended adults over 18 years of age the appropriate intake of phosphorus is 700 mg. Common phosphorus-containing foods are lean meat, eggs, milk, animal offal, kelp, Nuts, coarse grains. (5) Iron is the most content of trace elements in the human body, iron and the human body's life and its health are closely related to iron deficiency will lead to iron deficiency anemia, immunity decreased. China Nutrition Society recommended 50 years old More than men's or women's iron daily intake of 715 mg. Common iron-rich foods are animal liver, kidney, caviar, lean meat, potatoes, wheat bran.

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: Definition of inorganic salts: There are about 21 kinds of elements which have important physiological functions in the body. Among them, calcium, magnesium, potassium, sodium, phosphorus, sulfur and chlorine are more and more, and the amount of inorganic compounds is more Iron, copper, iodine, zinc, manganese, selenium, fluorine, chromium, nickel, molybdenum, silicon, tin, vanadium and cobalt content is extremely small, called trace elements .2, inorganic compounds in the general name of the salt. Formerly known as "minerals." Some elements of inorganic salts for the human essential nutrients, including potassium, sodium, calcium, phosphorus, iron, iodine and other 20 kinds of elements. With the maintenance of cells and liquid normal osmotic pressure, maintenance of neuromuscular excitement As a variety of acid system activator; constitute the ester of the base; hormones, vitamins, nucleic acid composition and regulate the body's acid and alkali balance and other important physiological functions. Increased or lack of disease, such as hyperkalemia, The explanation of the "inorganic salts" in the academic literature

Q: Why does inorganic salts affect chemical degradation of organic wastewater: Industrial organic waste water is highly toxic and stable pollutants, for such waste water is difficult to use conventional physical, chemical and biological methods. This paper summarizes the main processing technologies of biodegradable organic wastewater at home and abroad, including biological treatment, chemical treatment and physical treatment and various joint treatment processes. The methods or processes of various methods or processes are described.

Q: salt is organic or inorganic?: If you mean table salt, NaCl then it's inorganic. No Carbons there.

Q: How to extract inorganic salts in soil?: Find a piece of mud, with water, filter out the permeate, filter with filter paper. The liquid was placed in a beaker and dried to obtain white crystals
