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? Lemon flavor, citric acid, is it an inorganic salt?
Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain the normal level of citric acid is an important organic acid, also known as citric acid, no ...
Q:Is calcium carbide inactive?
Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
Q:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:What does salt form when it dissolves?
Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
Q:Definition of inorganic salts
In addition to hydrogen, oxygen, nitrogen, carbon, sulfur, organic compounds other than organic compounds are collectively referred to as inorganic salts. The inorganic salts required by the human body, according to the content in the body, divided into essential elements (hydrogen, oxygen, nitrogen, , Magnesium, phosphorus, chlorine, potassium, sodium 11) in the human body content, the need for larger also known as macro elements of the source 2, the rest of the various elements, regardless of content, can be collectively referred to as inorganic salts. More elements such as iron, magnesium, potassium, sodium, phosphorus, sulfur, chlorine and other elements, other elements such as iron, copper, iodine, zinc, manganese, drilling, etc., due to the existence of a small number, and some even trace Known as trace elements, 3, what is the "inorganic salt", the body contains elements in addition to carbon, hydrogen, oxygen three elements mainly in the form of organic matter, the rest of the various elements are in the form of inorganic matter, collectively referred to as inorganic Salts such as calcium, magnesium, potassium, sodium, phosphorus, scratch, sulfur and the like
Q:Which foods contain calcium-containing inorganic salts
Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat
Q:A colorless solution contains which inorganic salt?
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 disadvantages of inorganic salt deficiency and too much
high calcium, hypercalcemia can make nerve, muscle excitability to reduce the performance of fatigue, expression indifferent, tendon reflexes, severe patients may be mental disorders, stupor and coma; damage renal tubules, manifested as kidney Tubule edema, necrosis, basement membrane calcification, can cause kidney stones;
Q:What is the importance of the minor inorganic salts to living organisms?
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:How does inorganic salts maintain osmotic pressure and pH
Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
