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 are the differences between inorganic salts and salt?
Salt chemical name is called "sodium chloride", chemical symbol: NaCl
Q:How too much to eat too much inorganic salt
Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
Q:salt is organic or inorganic?
Inorganic -- does not contain carbon.
Q:Sodium bicarbonate is not an inorganic salt
Yes, organic refers to salts with carbon skeleton chains other than carbon and carbon oxides and carbonates, so sodium bicarbonate is an inorganic salt
Q:Inorganic salts in solution?
Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.
Q:how come inorganic salts increase surface tension of water?
It okorder.com/
Q:What is the relationship between inorganic salts and minerals?
Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
Q:does the water solubility of an inorganic salt increase or decrease as the temp of the water is increased. Exp?
IIRC, it depends on the salt.
Q:Why plasma osmotic pressure and protein, inorganic salt content
Plasma osmotic pressure is divided into crystalline osmotic pressure and colloid osmotic pressure.
Q:what are the advantages and disadvantages of taking health care agents?
Obviously, the advantages of taking health care agents are targeted, quick and effective; the disadvantage is to maintain the problem after the effect is like a hormone therapy, hormone therapy after the effect is very good, and physically strong after the virus may be recovered It is very effective, some poor physical is not the case. Poor physique, perhaps more suitable for "balanced dietary supplement".
