1.Structure of Sodium Hydrosulfite Description:

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:

1As reducing agent, hydrosulfite chemically reduces othercomponents by donating an electron or electrons

2As sulfonating agent, hydrosulfite adds sulfur to another chemical compound

3As cation source, hydrosulfite adds a cation, or sodium, to a product system

Q:Calcium is not an inorganic salt
Is a metal element
Q:in the ocean
Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.
Q:give me at least 5 substances
Inorganic Bases
Q:Why vegetables and fruits contain rich inorganic salts
Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier
Q:Inorganic salts are not nutritious
Nutritional substances are sugar protein fat three nutrients
Q:How to add inorganic salts
Helicobacter pylori can cause a variety of stomach problems, including gastritis, gastric ulcer, duodenal ulcer, non-ulcerative indigestion, gastric cancer. Therefore, the eradication of Helicobacter pylori has become an important measure for the treatment of modern gastrointestinal diseases. To identify patients with Helicobacter pylori infection, the clinical need for a high sensitivity, specificity, fast, simple, safe, inexpensive Hp diagnostic method, that is, carbon 14 breath test. The examination and painless, noninvasive, fast and simple, no cross the advantages of infection, experts at home and abroad have been recommended for the diagnosis of Hp gold standard, has been widely used in clinical practice.
Q:For patients with ulcerative colitis, which inorganic salt foods can eat?
Vegetables Cooking Choose fresh vegetables with more vitamins and inorganic salts.
Q:Does the inorganic salt affect the gpc molecular weight results?
GPC determination of molecular weight through the column when the molecular size of the molecular peak, the molecular weight of the early comparison of the peak, that is relatively large molecules in the GPC pillars can not pass, pass the molecules were detected out of the peak, This molecular weight is not absolute, since the GPC determination is actually the size of the molecule rather than the size of the molecule, and of course it is also possible to approximate the molecular weight of the molecular weight of the molecule. Large; exactly how their relationship, with GPC can not be determined, only through the standard liquid molecular weight to compare, this result is relative, not absolute.
Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.
Q:Effects of Minerals on Plants
Some will be plant death will help some will accumulate
