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: Can you please help me with this question and give me a website reference.
- Many of these materials enter the water through natural channels---minerals, salts and the like come from exposure to rocks, dirt and other inorganic materials.
- Q: What is the inorganic salt, is not the organic salt and is not the inorganic salt
- In fact, Na2CO3 is also inorganic salt ah! The Can not according to whether there is C to divide!
- Q: Consult the science and engineering, chemical and biological experts, plants absorb inorganic salts and water, then the absorption of inorganic salts in what form is absorbed into the way, is absorbed in the way of ions or in the way of the compound, And then only in the body only ionized into the ion state exists in the body. Grateful
- Of course it is ion
- Q: Is the inorganic salt related to the excitement
- In the natural state, both in the periphery and within the central nervous system, nerve impulses are conducted in the context of a single neuron. At the nerve tip (synaptic or on the muscle joint), nerve impulses cause the excitement or inhibition of the next cell by chemical transmission or electrical transmission.
- Q: Does the plant roots absorb inorganic salt ions must be active
- Plants absorb inorganic salts and do not necessarily absorb water. Plants absorb moisture and absorb inorganic salts are two relatively independent processes. Plants absorb moisture through the infiltration of root cells to absorb water, the process is essentially free of water diffusion process, neither the carrier nor the need for energy; and plant absorption of inorganic salts is carried out by means of active transport, This process requires the carrier and consumes the energy generated by cell metabolism. Of course, plant water absorption and absorption of inorganic salts are a certain association, inorganic salts to be dissolved in water to be absorbed, and inorganic salt ions in the transport of plants can not be separated from water.
- Q: What are the main physiological functions of inorganic salts?
- ) constitute the body of the important material
- Q: A. food gathering and digestion B. photosynthesis and diatom structures C. reproduction and osmosis D. wave and current motions
- its not a so try b or c those 2 are the most likely to be the right answers
- Q: would heterotrophic organism grow well in inorganic salt media? why or why not?
- No. Heterotrophs get energy from the environment in the form of chemical bonds within organic molecules (such as glucose). An inorganic salt medium would not supply the needed organic molecules. Your heterotroph would starve.
- Q: I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?
- it okorder /C005969/mi... "Mineral salts are inorganic (carbon-free) elements that turn to ash when burned. "
- Q: as a example potesium,sodium,magnees,calcium
- The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)
