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:Which solvents have some solubility in inorganic salts
A wide variety of dyes, dissolved complex. The original dyes are organic, but some salt, some metal complexes, some of the larger molecules of the fused ring compounds, some polymer heterocyclic compounds, in some common organic solvents in the solubility is better than disperse dyes Raw dyes and oil-soluble dyes (this is actually the raw material of solvent pigments, strictly speaking, not dyes). There are basically additives in the finished dyes, such as direct dyes, acid dyes, reactive dyes, cationic dyes and other water-soluble dyes will be added inorganic salts, disperse dyes, reducing dyes will be added sulfonate sodium dispersant. In addition, the dye and other chemical products, their purity requirements are generally very low, will allow the presence of certain insoluble impurities. So the organic solvent can not be completely dissolved dye products really is very common or even a normal phenomenon.
Q:the absorption of inorganic salts is how to absorb the form
Of course it is ion
Q:is table salt organic or inorganic, why?
Inorganic - NaCl - no complex carbon compounds.
Q:The lack of symptoms and food sources of several inorganic salts
Food sources of inorganic salts containing calcium Source: dairy products, beans, cereals, kelp and so on. Source: seafood, etc. Food of iron-containing inorganic salts Source: Fruits Containing iodine-containing inorganic salts Source (trace): seaweed, jellyfish, corn, mussels, etc. Zinc-containing inorganic salt food sources (trace): animal liver (viscera), fruit, peanuts, etc.
Q:Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
Three by: the beaker close to the glass rod;
Q:what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
For the best answers, search on this site www.okorder.com You're a riot, I swear. It amazes me how many people completely miss your plays on words. I'd stick with the "in" organic food. You know, the really trendy stuff like chai tea. Stay away from old, tired standbys like pizza and hamburgers. Macaroni and cheese, though, is like the tuxedo or the little black dress. It never goes out of style.
Q:Do inorganic mercury salts bioaccumulate?
Yes they do bioaccumulate. Mercury builds up for years and years, and eventually sits in a residue of pure mercury. - JJ
Q:what percent of dissolved salts found in seawater are minor inorganic salts, or trace?
Seawater varies in composition a little but generally is about 3.5% salts. Of this about 3.1% is sodium chloride. So the remaining 0.4% is the other salts (Magnesium, Calcium and Potassium mostly, followed by just about every natural element in the periodic table in trace amounts)
Q:Relation between salt concentration and amount of drops of saltwater on a penny?
The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
Q:is sugar and salt organic or inorganic?
sugar is organic salt is not. Sugar is made from carbon that's why it's organic in compound
