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:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:Will a potassium ion from the inorganic salt KBr attach to NH2 at the end of a carbon chain?
The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
Q:What does salt form when it dissolves?
Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
Q:How to add inorganic salts
Helicobacter pylori can cause a variety of stomach problems, including gastritis, gastric ulcer, duodenal ulcer, non-ulcerative indigestion, gastric cancer. Therefore, the eradication of Helicobacter pylori has become an important measure for the treatment of modern gastrointestinal diseases. To identify patients with Helicobacter pylori infection, the clinical need for a high sensitivity, specificity, fast, simple, safe, inexpensive Hp diagnostic method, that is, carbon 14 breath test. The examination and painless, noninvasive, fast and simple, no cross the advantages of infection, experts at home and abroad have been recommended for the diagnosis of Hp gold standard, has been widely used in clinical practice.
Q:What are the differences between inorganic salts and salt?
Salt chemical name is called "sodium chloride", chemical symbol: NaCl
Q:Cells are composed of water and inorganic salts or by organic matter and none
Cells are composed of water and inorganic salts or b
Q:List the major electrolytes released by inorganic salts when placed in water and explain how these electrolyte?
Which "inorganic salts" are you talking about? There are hundreds!
Q:How much of the body's inorganic salts account for the weight of the body?
The inorganic salts in the human body account for about 5%
Q:Is iodized salt inorganic or organic?
yes it is organic.
Q:How to get an inorganic salt
Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
