Commodity name: Sodium Hydrosulfite Na2S2O4 Sodium Hydrosulfite Sodium Dithionite Price

Molecular formula:Na2S2O4

Molecular weight:174

CAS Number 7775-14-6

H.S code 28311010

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?: Phosphorus-rich foods: fish, lean meat, untreated cereals, eggs, dried fruits, all kinds of seeds, etc. Almost all natural foods

Q:I am 18 years old, test the body of inorganic salt content of 3KG, people say that low. What is the value of this use? How can improve it?: The percentage of inorganic salts in human mass is 4 to 5%

Q:Is all the inorganic salts in the body related to life activities?: Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.

Q:Sodium bicarbonate is not an inorganic salt: Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt

Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts: to maintain the body's acid-base balance

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 minerals and trace elements?: Trace elements refers to the body weight of one thousandth of the body weight, daily requirements are generally in the following 0.01 grams can meet the physiological needs of the human body, as we often talk about iron, zinc, iodine, selenium, fluoride and so on. Calcium in the human body due to more content, the daily requirements of several hundred milligrams, it is a macro element.

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?: Dr. Henry A. Schroeder, the world's mineral authority, says that the minerals required by the human body are present in the water, meaning nothing more than those that exist in food.

Q:What is the composition of inorganic salts?: Inorganic salts are mineral nutrients that are present in the body and in food

Q:Would the amount of saltwater drops a penny surface could hold without spilling increase, or decrease, as the salt concentration increases? Also, maybe an explanation behind why it increases/decreases?Thank you!: The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
