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:Liver cancer diet should pay attention to what issues?
Balanced diet: liver cancer patients consume more, must ensure that there is enough nutrition. The easiest way to measure the nutritional status of a patient is to maintain weight. And to maintain the normal level of weight, the best way is to maintain a balanced diet, requiring patients should eat more fresh vegetables, and half should be green leafy vegetables.
Q:Acids, salts, and metals are examples of?
Acids, D. water soluble inorganic chemicals salts, D. water soluble inorganic chemicals metals E. sediment
Q:give me examples of organic, inorganic, acid, base, salt.?
Inorganic Bases
Q:What are the important physiological effects of inorganic salts in cells
Maintain the normal life of the organism
Q:Will a potassium ion from the inorganic salt KBr attach to NH2 at the end of a carbon chain?
The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.
Q:Does the milk contain inorganic salts?
Calcium, phosphorus, potassium .1L milk can provide 1g of calcium, and milk calcium and phosphorus ratio of 1.2: 1, close to human milk (human milk 1: 1), digestion and absorption rate, it can ensure that the baby's calcium Need milk milk in the very few, only 0.2mg / 100g, for the human milk 1/5, the baby, such as milk-based food feeding, the need to timely add iron and vitamin C foods such as egg yolk, liver mud, In addition, the milk also contains copper, zinc, manganese, iodine, molybdenum and other trace element
Q:What does salt form when it dissolves?
Most inorganic salts are ionic in nature and therefore it will dissociate in ions. For example Copper sulphate will dissociate in Cu+2 and SO4 -2 ions. If the dissociation energy of the salt is too high, it will remain partially or completely as salt in the solution. large number of organic salts do not dissociate completely and the solution will contain Ions and salt - both.
Q:The presence of inorganic salts
The presence of inorganic salts is mostly present in the ionic state in a small number of compounds
Q:What inorganic salts are needed for seeds?
Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid
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
