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, are you a trade company or factory?
We are a trade company.
2, what is your main product?
My main product is ammonium chloride all grade. We have special advantage in FEED
GRADE.
3, how do you control the quality?
We do quolity control by the factory testing department. We also can do FDA,BV, SGS or any orther Third-party testing.
4, 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.
5, how long time you can make the shipping?
We can make the shipping within 5-10day after confirm the order.
6, 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: CuMnFeNior ZnAlso metal calcium reacts with molecular hydrogen to form a compound. Which statement concerning this compound is not true?It's formula is CaH2it is ionicsolid at room tempwhen added to water, reacts to produce h2 gaswhen added to water, forms acidic solutionMy guess was going to be that it is not ionic, but i'm not 100% positive.Can anyone help me with these chemistry questions? Or atleast point me to some webpage that might help. Please and thank you.
- Only Zn compounds form colorless or white salts. The second question would be the last answer, which is false. It forms an alkaline solution when added to water.
- Q: Why is the inorganic salt left after the burning of the food
- Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.
- Q: Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
- (2) to participate in and maintain the metabolic activity of the organism.
- 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: An inorganic salt is dissolved in water and yields a solution that has a color. Make a statement about the type of element the substance contains that casuses the color.Thanks!
- Many inorganic salts form colored solutions . pper ( II) sulfate ( Blue ) nickel (II) acetate = green, mangaanse ( II) chloride = pink, iron(III) chloride = yellow, potassium dichromate, orange and so many more Can you be more specific ?
- Q: Why are inorganic sodium salts much better soluble in ethanol than potassium salts?
- Potassium's lone electron is much more easily transferred to produce a potassium ion than is sodium's because of its electronic structure so that any potassium salt is more ionic in nature than is its analogous sodium counterpart. Since ethanol is not very acidic (polar) it solublizes less polar materials preferentially over more polar ones. Therefore, sodium salts will, generally, be more soluble in ethanol than will be potassium analogs.
- Q: What are the main physiological functions of inorganic salts?
- enzyme composition and activator
- Q: What is the risk of low inorganic salt?
- Iodine content in the human body is much lower than 1/10000 is a trace element. Function iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases endemic goiter and local minor illnesses. Excessive symptoms iodine goiter, iodine thyrotoxicosis. Supply Adult 150ug Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
- Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?
- 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: And what I specifically need are salts with Bromide, Chloride, Phospate and Carbonate ions.Thanks for any help.
- 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.
