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: What to eat can promote the absorption of inorganic salts
- Transpiration on the absorption of inorganic salts has little effect, the book or which exercises on the image shows the problem
- Q: Does the inorganic salt fight the mass spectrum?
- Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
- Q: People do not eat salt tears with no inorganic salt
- I suddenly think of a science program that found a place a strange person, never drink water, then a variety of surprises. Finally, the scientist came out to explain that he can get the daily water needed from the food.
- 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: What are minerals and trace elements?
- Minerals Trace elements are inorganic salts, which are widely found in nature - soil, sea water, animals, plants. It is to maintain the normal life of the human body indispensable. They are both the body of the composition, but also the activities of life participants and regulators, and therefore known as the elements of life, and they are the body can not synthesize their own nutrients.
- Q: What are the important physiological functions of inorganic salts in cells
- Maintain intracellular acid-base balance, regulate osmotic pressure, maintain cell morphology and function. Such as: blood calcium and potassium ions.
- Q: what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?
- The organic part is where blood cells are manufactured. The inorganic part is for structural strength
- Q: What are organic and inorganic salts?
- An organic salt is a salt containing an organic ion ( carbon atoms ) The reaction product of an organic acid and an inorganic base, for example, sodium acetate (CH3COONa) from the reaction of acetic acid (CH3COOH) and sodium hydroxide (NaOH). The Organic ion, here, is CH3COO- Inorganic compounds come principally from mineral sources of non-biological origin. The modern definition of inorganic compounds often includes all metal-containing compounds, even those found in living systems. So, Inorganic salts are salts of such elements (salts that don't contain carbon atoms) For eg: NaCl, KCl, BaCl2, Al2SO4, etc
- Q: How to extract inorganic salts in soil?
- Dissolve, filter, evaporate
- Q: The application of various inorganic salts in the human body?
- Silicon in the water was partial silicic acid form absorbed by the body, mainly distributed in human skin and connective tissue, in the process of skeleton has a physiological role in promoting the development of bone development. Silicon is also involved in the metabolism of polysaccharides, is to form some glucose The main component of the aminopolysaccharide carboxylic acid.
