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:are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?
water and salt aren't foods. There is no caloric value in them, so they cannot be foods. We live on earth. All foods have an organic origin.
Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
When the boron deficiency occurs, pollen tube germination is affected and poor fertilization leads to seed formation.
Q:What fruit contains more minerals?
Persimmon contains a lot of carbohydrates, per 100 grams of persimmon containing 10.8 grams, mainly sucrose, glucose and fructose, which is why we feel very sweet persimmon persimmon in the other nutrients are not only contain a small amount of fat , Protein, calcium, phosphorus, iron and vitamin C. In addition, persimmon is rich in pectin, it is a water-soluble dietary fiber, a good laxative effect, for correcting constipation, to maintain normal intestinal flora Growth and so have a good effect.
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:What is the inorganic salt, is not the organic salt and is not the inorganic salt
I have not come across the salt area is divided into inorganic and organic, only heard of inorganic and organic matter. Probably the organic acid metal salt.
Q:is sugar and salt organic or inorganic?
Healthy compounds have carbon in them at the same time inorganic compounds should not have carbon. For example, sugar (C6H12O6) has six carbons, and is for this reason an organic compound. Water then again (H2O) does now not have a carbon in it and is an inorganic compound.
Q:A colorless solution contains which inorganic salt?
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:Is bromine an inorganic salt?
Bromide is an anion which joins with a cation to make a salt like Sodium Chloride (table salt) Bromine is a liquid bleach, similar to chlorine gas. oganic compounds are those which have carbon or sulphur base
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:What is the difference between organic salt and inorganic salt?
one is organic while the other is inorganic
