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:Can basal salt cause disease or illness?
the web page (below) discusses: Basal Salt Mixtures The use of balanced salt solution (BSS) in cell and tissue culture is generally attributed to early workers in the field. In 1885, Sydney Ringer developed a solution of inorganic salts designed to maintain contractility of mammalian heart tissue. A less specific salt solution was designed by Tyrode for use in work with primary mammalian cells. Tyrode's salt solution became the accepted fluid for diluting protein components of media of natural origin. Since that time, many other balanced salt solutions have been developed for use in cell and tissue culture. The current role of balanced salt solution in cell culture is multi-faceted and can be divided into four principle functions. see web page for extensive discussion on the good things about it
Q:What are the nutritional requirements for bacterial growth?
For inorganic salts: bacteria need a variety of inorganic salts to provide a variety of elements of bacterial growth, which requires the concentration of 10.3 ~ 10.4mol / L elements for the common elements, the need for concentration in the
Q:Where can I find a list of all inorganic salts?
That list is near endless. There are countless inorganic cations and organic groups that can combine with these ions. Pretty much every metallic element in the periodic table will form cations with bromide and chloride. Not sure about phosphate, but most metals will bind with it. Carbonate will be trickier, as some ions are too acidic and will decompose the carbonate (iron(III) is an example, and it will form the oxide instead, liberating CO2 in the process). Aside from simple elemental ions, there are also polyatomic cations (such as ammonium) and lots of complexes that will form compounds with these anions.
Q:What is the difference between inorganic and inorganic salts?
Organic matter is defined as: all substances that are carbon-containing substances, organic substances other than carbon dioxide, carbonates, carbon monoxide, cyano substances, elemental carbon itself, etc. are generally used in the field of organic chemistry, including natural generation Of organic matter and synthetic organic matter (especially polymer-based organic matter)
Q:What is the lack of inorganic salts for children?
Zinc salts, iron salts and calcium salts
Q:What are the physiological functions of inorganic salts
An important component of cells and organisms
Q:The effect of inorganic salt medium and the difference with enrichment medium
The enrichment of nutrients is based on the basis of nutrition based on some kind of nutrient-rich substances for the target cells, the purpose is to increase the number of target cells, so that the formation of growth advantages, so as to achieve the purpose of separation, such as we have to be separated Pseudomonas aeruginosa, this bacteria particularly like blood, so you can add blood in the medium, so that the formation of growth advantages of this bacteria.
Q:What is an inorganic salt?
I think inorganic salts mean salts that do not contain organic ionic groups
Q:Are plants absorbing water and inorganic salts only through root tip or wrong?
Plants through the leaves can also absorb water and inorganic salts, but the root tip is the main part of the plant to absorb water and inorganic salts.
Q:After a lot of sweating, the amount of drink with inorganic salt drink right?
It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink
