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

UN number 1384

Class 4.2

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: What is inorganic salt
Inorganic salts are important for the structure of tissues and cells. Hard tissues such as bones and teeth are mostly composed of calcium, phosphorus and magnesium, and soft tissue contains more potassium. The inorganic salt ions in the body fluid regulate the permeability of the cell membrane, control the water, maintain normal osmotic pressure and acid-base balance, and help transport the general element to the body, participate in nerve activity and muscle contraction. Some are inorganic or organic compounds that are involved in many important physiologic functions, which are constituents of enzymes that make up enzymes, hormones, vitamins, proteins and nucleic acids, or as activators of various enzyme systems. For example: to maintain the heart and brain activity, to help the formation of antibodies, play a useful role in the human body.
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: Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
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: The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?
Mineral is a naturally occurring compound or natural element in the crust, and minerals, like vitamins, are essential elements of the body, and minerals are not self-contained. Generated, synthetic, daily intake of minerals is basically determined, but with age, gender, physical condition, environment, working conditions and other factors are different.
Q: Consult the science and engineering, chemical and biological experts, plants absorb inorganic salts and water, then the absorption of inorganic salts in what form is absorbed into the way, is absorbed in the way of ions or in the way of the compound, And then only in the body only ionized into the ion state exists in the body. Grateful
Absorbed in an ionic state.
Q: Does the plant roots absorb inorganic salt ions must be active
Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
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
Q: What is the difference between organic salt and inorganic salt?
An organic salt contains a cation or anion that is derived from an organic compound (compounds that contain carbon), e.g. acetate (anion) from acetic acid, or triethyl ammonium (cation), from triethylamine. An inorganic salt is one that doesn't contain an organic cation or anion. Carbonates are not considered organic compounds, even though they contain carbon.
Q: Does the apple contain inorganic salts and vitamins?
Yes, the fruit is rich in these two nutrients, especially apples
