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: Urine in the inorganic salt content is higher than the original urine: Because the original urine to be re-absorption

Q: Can inorganic salts be tested by LC / MS?: LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.

Q: Like the role of B, Fe, Mg, Ca, Mn, Cu, Cl, P, S, N ...., the more specific the better (college entrance examination range): 1. constitute the body tissue material .2. Regulate the physiological function .3. To participate in the regulation of body fluid balance and maintain the body's acid-base balance .4 cells of some complex compounds of the important components

Q: bonded to an acid molecule called- such as potassium citrate?Thanks: A mineral is mostly an inorganic salt that can form naturally in the earth. Potassium citrate on the other hand is an organic salt which is formed by addind an potassium base to citrate acid (citrate acid is an acid that is found in fruits and is termed organic as it is mostly has carbon atoms in it)

Q: Are the inorganic salts mineral and they are soluble in water?: Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?

Q: what is the function of the organic part of bone matrix?of the inorganic part(bone salts)?: For the best answers, search on this site www.okorder You're a riot, I swear. It amazes me how many people completely miss your plays on words. I'd stick with the "in" organic food. You know, the really trendy stuff like chai tea. Stay away from old, tired standbys like pizza and hamburgers. Macaroni and cheese, though, is like the tuxedo or the little black dress. It never goes out of style.

Q: Eat what food can add inorganic salt: Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. According to their content in the body how much can be divided into constant elements and trace elements two categories. The body is actually composed of various elements (macro and trace). Many of these mineral elements are essential components of the enzyme, which can regulate a variety of physiological functions (such as maintaining osmotic pressure, oxygen transport, muscle contraction, nervous system integrity), but also tissue and bone growth and maintenance necessary. Some (such as calcium, phosphorus, sodium, magnesium, sulfur, chloride) content is large, while others are only trace. Human essential trace elements are cobalt (such as vitamin B12), copper, fluorine, iodine, iron, zinc, chromium, selenium, manganese, molybdenum In terms of its impact on experimental animals, nickel, tin and arsenic should also be considered necessary. Most minerals (except zinc) are widely distributed in a variety of foods and can be fully supplemented by balanced and diversified diets. However, there is a need for additional supplements to patients who have been relying on intravenous nutrition for long periods of time, infants and older persons, or because of the lack of regionalities caused by soil and water quality.

Q: List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.: Which "inorganic salts" are you talking about? There are hundreds!

Q: What is the disease of inorganic salt crystals?: But if the urine turbidity, but also accompanied by fever, low back pain, increased frequency of urination and other phenomena, there may be inflammation of the urinary system, should go to the hospital for timely diagnosis and treatment of doctors.
