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:Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
Q:Are there any differences between minerals and inorganic salts?
There are differences, some minerals exist in organic matter, and some minerals are inorganic salts. Inorganic salts are inorganic.
Q:What is the difference between organic salt and inorganic salt?
An organic salt contains a cation or anion that is derived from an organic compound (compounds that contain carbon), e.g. acetate (anion) from acetic acid, or triethyl ammonium (cation), from triethylamine. An inorganic salt is one that doesn't contain an organic cation or anion. Carbonates are not considered organic compounds, even though they contain carbon.
Q:Which crop feet can provide C N inorganic salts for fungal growth
Plant growth requires a variety of inorganic salts, which require the most is nitrogen, phosphorus, potassium containing inorganic salts. If a lack of some inorganic salts, plants can not grow normally. Kind of crops need fertilization, farm manure contains organic matter, the microbial decomposition of the soil will produce a large number of inorganic salts for plant growth and utilization, the role of fertilizer is to provide a variety of plant growth of inorganic salts. Therefore, in agricultural production, the application of fertilizer and farm manure is intended to provide a variety of inorganic salts for crops.
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:Why is sodium chloride(salt) an inorganic compound?
Yes it is considered to be organic only if the compound contains carbon. Oxygen and Hydrogen have no bearing on that, for example CO2 is organic, whereas H2O is not.
Q:Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.
Inorganic salts that inorganic compounds in the salt, formerly known as minerals, in biological cells generally only fresh weight of 1% to 1.5%, the current body has found more than 20 species, including a large number of elements Ca Ca, P, K Ka Sulfur, selenium, molybdenum, fluorine, chromium, cobalt, iodine and so on. Although the inorganic salt in the cell, the body content is very low, but the effect is very large, if the attention of diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, Salt to maintain a normal level.
Q:Inorganic salt is not salty
(About 40%): super hot, feel hot porridge, and then slightly sweet and pain coexist. , For 2 days to retire (98% pure concentrated sulfuric acid can not drink).
Q:How can experiments prove that there are inorganic salts in the leaves of plants
The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
Q:What are the important physiological effects of inorganic salts in cells
Composition of cells in some important compounds,
