Product Description:

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: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:Effect of Inorganic Salts on Viscosity
possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
Q:What are the effects of water, inorganic salts, carbohydrates, proteins, fats and vitamins?
The main physiological functions of minerals: 1. constitute the body of the material. (Such as calcium, phosphorus, magnesium is a bone, an important component of the teeth.) 2. Regulate the physiological function. (Minerals are often enzymes activators.) 3. Participate in the regulation of body fluid balance and maintain the body's acid-base balance.
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:What is inorganic salt food
Vegetables Cooking Choose fresh vegetables with more vitamins and inorganic salts.
Q:What are the physiological functions of inorganic salts
Maintain the life of cells and organisms
Q:Does the lack of inorganic salts cause convulsions?
The lack of important substances in the salt body is indeed the use of salt to protect the health of important substances than the calcium and phosphorus main body bone calcium blood coagulation muscle contraction and nerve cell regulation very important phosphorus calcium with the same function of food are preserved phosphorus body lack of calcium muscle spasms Can be rash dyspnea gastrointestinal paralysis and other body no phosphorus calcium calcium phosphate can be used to make bone calcium and phosphorus with a reasonable reason to play its role in the use of salt my body's non-essential body about 50 grams of salt according to 0 --- 2 5 grams To follow the excreta outside the body need to be added or otherwise the body of the production capacity of the body is extremely lack of salt can be fainting disease to speed up or even cause muscle weakness in the iron content and its role is not important in vivo iron deficiency anemia and other iron deficiency
Q:What substances can detect inorganic salts
Chemistry or creatures
Q:Several inorganic salts are lacking in symptoms and food sources
Ingredients of calcium-containing inorganic salts: dairy products, beans, grains, kelp and so on
