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: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:ATP components are not inorganic salts
ATP components are not inorganic salts
Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
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 minerals and trace elements?
Trace elements refers to the body weight of one thousandth of the body weight, daily requirements are generally in the following 0.01 grams can meet the physiological needs of the human body, as we often talk about iron, zinc, iodine, selenium, fluoride and so on. Calcium in the human body due to more content, the daily requirements of several hundred milligrams, it is a macro element.
Q:Effects of Minerals on Plants
Root absorption of mineral elements is based on cell uptake. But the root of the absorption of mineral elements has its own characteristics. First, the roots of salt and water relative absorption. As the root of the salt and water absorption mechanism is different, the absorption is disproportionate. The second is that the root system is selective for the absorption of mineral elements. That is, some of the absorption of some ions, while the absorption of some ions with little or no absorption. The third is that single salt poison and ion confrontation. The general cationic toxic effect is obvious, the anion toxic effect is not obvious. In the single salt solution if adding a small amount of other valence of different metal ions in the salt, single salt poisoning phenomenon will be reduced or disappeared. This effect of ions is called ion confrontation. Generally in the periodic table of different groups of metal elements between the ions will have a confrontation. Plants as long as a certain concentration, a certain proportion of a variety of salt mixture in order to normal growth, this solution is called the balance solution. In the fertilization should be very careful.
Q:Where are the parts of the bryophyte absorb water and inorganic salts?
Moss moss moss, moss Gang, moss root through the fake root absorption, that is, the use of cell penetration technology, moss Gang has evolved out of the root, so you can directly through the relatively low roots to absorb Oh
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: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: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.
