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

5.FAQ

1, how about your packing?

  My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag. 

 

2, how long time you can make the shipping?

  We can make the shipping within 5-10day after confirm the order. 

 

3, why you buy from me?

  We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.

Q:Several inorganic salts are lacking in symptoms and food sources
Ingredients of calcium-containing inorganic salts: dairy products, beans, grains, kelp and so on
Q:Are there any differences between minerals and inorganic salts?
For example, iodine in kelp, calcium lactate in sour milk, etc. These minerals are not inorganic salts.
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:Inorganic salt through what way into the human body
You eat every day
Q:What are minerals and trace elements?
81 species were detected on the basis of the human body. 81 kinds of elements in the body of the arrangement is very tight combination, and more less will not work. Human anatomy found that there are 74 kinds of serum, 54 kinds of brain, 49 kinds of heart, 50 kinds of liver, thymus 18 species. They constitute the most basic unit of the human body, human life, old, sick, dead and all elements related to the body. According to the elements in the human body content is different, can be divided into macro elements and trace elements two categories. Accounting for more than 0.01% of the total body weight of the elements, such as carbon, hydrogen, oxygen, nitrogen, calcium, phosphorus, magnesium, sodium, etc., called macro elements; , Zinc, copper, manganese, chromium, selenium, molybdenum, cobalt, fluorine, etc., known as trace elements. Trace elements in the human body content is really minimal, such as zinc only the total weight of the human body of thirty-three parts per million. Iron is only sixty thousandths.
Q:Inorganic salt effect
Ca2 + is the animal bone and teeth (containing CaCO3) composition, and blood coagulation and muscle contraction has a regulatory role, if the content is too low, the animal will appear muscle twitch. K + is a variety of enzyme activator, for the plant starch and protein synthesis and animal nerve impulse conduction and muscle contraction also plays an important role. Fe is a component of hemoglobin and cytochrome, and iron-containing enzymes are indispensable when chlorophyll is formed in plants. Another example is Na + for animal heart beat, nerve excitement is indispensable.
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".
Q:Anyone familiar with GC? Is it safe to put an alcohol + inorganic salt water mix into a GC?
Do not let salts enter the GC. You will have to perform an extraction step and run that. Salts can precipitate in the column or degrade into reactive species that can corrode the GC. Water is OK since it will not destroy the column (I've run aqueous solutions before), but salts are not.
Q:how come inorganic salts increase surface tension of water?
Put in in a narrow tube. The narrower it is, the more surface tension it has at the meniscus.
Q:Minor inorganic salts are needed for these functions.?
its not a so try b or c those 2 are the most likely to be the right answers
