CAS Number 7775-14-6

H.S code 28311010

UN number 1384

Class 4.2

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:Would the amount of saltwater drops a penny surface could hold without spilling increase, or decrease, as the salt concentration increases? Also, maybe an explanation behind why it increases/decreases?Thank you!
The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
Q:What is an inorganic salt?
Inorganic salts are not just salts of carbon-free salts, and some salts containing carbon are apparently also inorganic salts such as K2CO3, sodium bicarbonate, etc.
Q:What are the important physiological effects of inorganic salts in cells
Maintain the balance in the body
Q:The power of the water and inorganic salts in the plant is derived from the action of the plant
Capillary siphon, as well as leaf water transpiration power.
Q:Does the inorganic salt fight the mass spectrum?
Can it be specific? What mass spectrometer, which inorganic salts. Do EI need samples can be vaporized, inorganic salts obviously not appropriate
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!!
Q:People lack the inorganic salt will be what disease
iodine deficiency can lead to illness, children and adult goiter, hyperthyroidism and so on.
Q:Several kinds of inorganic salt food sources?
Milk containing calcium, spinach iron, kelp containing iodine, oysters containing zinc, carrots containing A, tomatoes containing C, mushrooms with B1, sun can get D
Q:Are plants absorbing water and inorganic salts only through root tip or wrong? The
This is wrong.
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
