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: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:How much of the body's inorganic salts account for the weight of the body?: The inorganic salts in the human body account for about 5%

Q:The human body does not intake of minerals can be? Lack of minerals on the human body what kind of harm?: Body weight: 96% is organic matter and moisture, 4% for the inorganic elements of the body about 50 kinds of minerals, in these inorganic elements, has been found in about 20 elements constitute the body tissue, to maintain physiological function, Biochemical metabolism necessary, in addition to C, H, O, N mainly in the form of organic compounds, the rest are known as inorganic salts or minerals can be divided into constant elements and trace elements two categories.

Q:What are the important physiological effects of inorganic salts in cells: Composition of cells in some important compounds,

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:CuMnFeNior ZnAlso metal calcium reacts with molecular hydrogen to form a compound. Which statement concerning this compound is not true?It's formula is CaH2it is ionicsolid at room tempwhen added to water, reacts to produce h2 gaswhen added to water, forms acidic solutionMy guess was going to be that it is not ionic, but i'm not 100% positive.Can anyone help me with these chemistry questions? Or atleast point me to some webpage that might help. Please and thank you.: Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.

Q:What are the physiological functions of inorganic salts: Maintain cell osmotic pressure and acid-base balance

Q:Why plasma osmotic pressure and protein, inorganic salt content: Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.

Q:I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!: Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr /cyber/kidswrld/plan...

Q:What is the risk of low inorganic salt?: Phosphorus into the body of phosphorus containing 750-800mg about 1% of body weight, mineral weight of 1/4. Of which 87.6% in the form of hydroxyapatite bone salt stored in the bones and teeth, 10% with protein, fat, sugar and other organic matter combined constitute soft tissue, the rest distributed in the muscle, skin, nerve tissue and other tissues and membranes Of the ingredients. Function Phosphorus is present in every cell of the human body, which is indispensable for bone growth, tooth development, renal function and nerve conduction. Phosphorus is a component of nucleic acids, phospholipids and certain enzymes, which promotes growth and tissue repair. It helps carbohydrate fat and protein utilization, regulates glycogen breakdown, and participates in energy metabolism. Phospholipids are the major components of the cell membrane, which are related to the permeability of the membrane. Phosphate can regulate the metabolism of vitamin D, to maintain the stability of calcium within the environment. Lack of disease  phosphorus deficiency when the mental confusion, cranial nerve palsy, transport disorders, muscle weakness, hypothyroidism, anorexia, joint stiffness, abnormal blood, urinary calcium increased. Typical cases  hyperphosphatemia, renal dysfunction, or hypoparathyroidism and hypothyroidism and other endocrine diseases can also occur. Too many symptoms  nerve excitement, tetany and convulsions. The physiological requirement of phosphorus is 12.3mg / kg / d. Calcium / phosphorus ratio in the 2: 1-1: 2 appropriate range. Food sources  food in the meat, fish, milk, beans and hard shells and other phosphorus more.
