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

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: How does inorganic salts maintain osmotic pressure and pH
- Osmotic pressure to the concentration of inorganic salts affect the distribution of water molecules inside and outside the cell ~ to adjust the osmotic pressure, when the extracellular fluid concentration is greater than the intracellular fluid when the performance of water loss, otherwise the water.
- Q: Definition of inorganic salts
- In addition to hydrogen, oxygen, nitrogen, carbon, sulfur, organic compounds other than organic compounds are collectively referred to as inorganic salts. The inorganic salts required by the human body, according to the content in the body, divided into essential elements (hydrogen, oxygen, nitrogen, , Magnesium, phosphorus, chlorine, potassium, sodium 11) in the human body content, the need for larger also known as macro elements of the source 2, the rest of the various elements, regardless of content, can be collectively referred to as inorganic salts. More elements such as iron, magnesium, potassium, sodium, phosphorus, sulfur, chlorine and other elements, other elements such as iron, copper, iodine, zinc, manganese, drilling, etc., due to the existence of a small number, and some even trace Known as trace elements, 3, what is the "inorganic salt", the body contains elements in addition to carbon, hydrogen, oxygen three elements mainly in the form of organic matter, the rest of the various elements are in the form of inorganic matter, collectively referred to as inorganic Salts such as calcium, magnesium, potassium, sodium, phosphorus, scratch, sulfur and the like
- Q: How to isolate the effects of inorganic salts on enzyme solubility
- The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.
- Q: A solution is known to contain an inorganic salt of one of the following elements. The solution is colorless. The solution contains a salt ofa. Cub. Mnc. Fed. Nie. Zn
- Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.
- Q: In order to prove that magnesium is an essential salt for soybean life, two soybean seedlings with the same growth status are taken, one of them is cultured in magnesium-containing culture medium and the other is cultured in (). A. Pure water B. Sand without sand. Water containing only magnesium. Media containing no magnesium
- Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.
- Q: Please help me!
- This is because NaCl does not contain Carbon. It is usually compounds that contain Carbon which can be considered ORGANIC compounds. :)
- Q: What does salt form when it dissolves?
- ions. depending on which kind of salt: NaCl -> Na+ + Cl-
- Q: Which minerals is richest source of Inorganic Salts ?
- Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.
- Q: The application of various inorganic salts in the human body?
- Protein synthesis, nerve conduction, muscle contraction, body temperature regulation, complete cell maintenance and energy metabolism are inseparable from the magnesium.Many studies have confirmed that people lack of magnesium, often headache, irritability, emotional stress, limb weakness, depression insomnia, Children will grow and develop obstruction.Human blood levels of the body if the sudden decline, can lead to arrhythmia or coronary heart spasm, decreased immunity, women will appear dysmenorrhea.
- Q: I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?
- it okorder /C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "
