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:What is the physiological function of inorganic calcium
- Maintain the life of cells and organisms
- Q:in the ocean
- Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.
- Q:Inorganic salt is not salty
- HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.
- Q:What is the difference between inorganic and inorganic salts?
- Inorganic matter: the definition of inorganic matter in the narrow sense is: organic matter other than substances, including salts, inorganic acids, alkali and other compounds and elements and so on.
- Q:Is the inorganic salt related to the excitement
- Nerve impulses are transmitted in all or no way without attenuation along the nerve fibers. The conduction velocity of the action potential varies depending on the type of the animal, the type of nerve fibers, the thickness and the temperature.
- 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:salt is organic or inorganic?
- any salt is ionic which means ionic bonds, and carbon mostly forms covalent bonds, so it is very very unlikely that a salt contains carbon making it organic so most if not all salts are inorganic
- Q:I'm said that with the increase of temperature the inorganic salts will decrease. Will that be correct?
- IIRC, it depends on the salt.
- 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:Of the dissolved salts found in seawater, _____ % are minor inorganic salts, or trace.
- it's definitly one of these: 99.28 .72 72 50 i think it's 99.28. lemme no if you get it right!!
