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

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:Is the inorganic salt the same as the saline?: Saline is sodium chloride solution, most people use the point is 0.9%.

Q:What is the difference between "organic salt" and "inorganic salt"? What is the difference between "organic salt" and "inorganic salt"?: Inorganic salts are inorganic acids (hydrochloric acid, sulfuric acid, nitric acid) with alkali generated by the reaction of the salt is called inorganic salts. Inorganic salts are salts that do not contain carbon, and organic salts are carbon-containing but do not include carbonates.

Q:An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!: Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?

Q:The difference between the ignition of inorganic salts and organic matter: Calcium is an important part of bones. Calcium deficiency can lead to osteomalacia, osteoporosis and so on. China Nutrition Society recommended 18-50 adult calcium intake of the appropriate daily intake of 800 mg; 50 years old after the elderly taste 1000 mg. Common calcium-rich foods are milk, yogurt, oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily and so on.

Q:Chemical formula The longest inorganic salt: The longest can have a large number of atoms, I remember the teacher said is more than a hundred different atoms or groups

Q:what is the function of salts in DNA extraction?: DNA can be purified for DNA sequencing or for restriction digestion by precipitation in an alcohol/water mixture in the presence of a high concentration of inorganic salt. DNA is recovered from the aqueous solution by addition of salt to final concentrations of 0.8M LiCl, 0.3-0.5M NaCl, NaOAc, or 2.5M NH4Ac and an appropriate volume of alcohol (30%-50% final percentage isopropanol; 60%-80% final percentage ethanol), storage for a brief period of time at -20°C or -70°C, followed by centrifugation. Subsequent desalting of the DNA pellet involves rinsing in 70% alcohol, recentrifugation and re-suspension in appropriate buffer.

Q:Please help me!: something is considered an organic compound if it contains Carbon, Oxygen or Hydrogen which every living being contains. If it lacks all 3 then its inorganic, if it has one or more then its considered organic

Q:Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: There is no essential difference, the measurement method is different, so the result is different, the former is the burning method, which is the chemical method or instrument method

Q:Inorganic salts are not nutritious: Nutritional substances are sugar protein fat three nutrients

Q:Children eat what to add the body of inorganic salts: Such as fruits, vegetables, beans or soy products, kelp, eggs and so on. Eat hot and humid food: watermelon, bitter gourd, peach, ebony, strawberry, tomatoes, cucumber, mung bean and so on.
