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:How much of the body's inorganic salts account for the weight of the body?
The inorganic salts in the human body account for about 5%
Q:give me at least 5 substances
Organic: methane CH4, propanone CH3COCH3, glucose C6H12O6, ethanol CH3CH2OH, ethene C2H4 Inorganic: CO2, SO3, NO, NO2, SO2 Acid: HCl, HNO3, H2SO4, HCOOH, H2CO3 Base: NaOH, KOH, CaO, CaCO3, MgO Salt: NaCl, KCl, MgCl2, CaCl2, KBr
Q:Magnesium can constitute chlorophyll, which reflects the nature of inorganic salts
norganic salt function (1), is the structural component of cells.Many inorganic salts are an important part of some complex compounds in cells.Example: Mg2 + is a necessary component of chlorophyll molecule; Fe2 + is the main component of hemoglobin; calcium carbonate is animal And the body of the bone, an important component of the teeth.
Q:Does the plant absorb some of the inorganic salt?
While the plant absorbs inorganic salts through the way of active transport, the process requires the carrier and the need to consume the energy generated by cell metabolism.
Q:By balancing the benefits of dietary supplementation with inorganic salts, what are the advantages and disadvantages of taking health care agents?
Diet supplementation of inorganic salt or the nutritional needs of the human body is the normal diet of human absorption, rather than through deliberate conditioning to mobilize the body's ability to absorb (including deliberately balanced diet), that is, add inorganic salt only conventional diet Yes, no other adjustment supplement is its benefit, that is, healthy people do not need to like non-healthy state as a way to seek additional, this is his advantage.
Q:RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?
Early society has not yet entered the era of industrial development, then the life of drinking tap water pollution, but also relatively clean, in the case of completely pollution-free, of course, stored in the water only a trace of beneficial minerals on the human body, through our daily life But now the industrial development, destruction of our water, we can not for the slightest beneficial to the human body of minerals, and to absorb a lot of harmful substances in the body it! Moreover, the minerals in the water and the water in the water, Is not the main source of human needs, we can get from the daily diet of the human body needs 99.9% of the minerals, water contains organic matter, inorganic matter is not necessarily absorbed by the human body, or even harmful is not necessarily.
Q:citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!
Simmons Citrate Medium
Q:If you boil down salt to a vapor form and breathe it in, can it kill you? or do you have to mix it with another chemical for it to become deadly. (Or will the vapor be so hot it will burn your lungs)
The boiling point of salt is incredibly high. Like thousands of degrees Celsius high. If you can actually manage to boil salt I would not recommend inhaling it.
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:Which foods contain calcium-containing inorganic salts
Calcium and inorganic salts are two concepts, bother you to go back and turn the chemical book and then ask, inorganic salt can eat
