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 inorganic salts be tested by LC / MS?
- LC-MS mass spectrometer for organic matter, inorganic salts can not be atomized not applicable, and will pollute the instrument.
- Q: What is the inorganic salt
- Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has been found in more than 20 species, including constant elements of calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium, trace elements are iron, zinc, , Chrome, cobalt, iodine, etc. If you pay attention to diet diversification, eat less animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, the body can make the inorganic salt to maintain normal level.
- Q: Children eat what to add the body of inorganic salts
- Such as fruits, vegetables, beans or soy products, kelp, eggs and so on. Eat hot and humid food: watermelon, bitter gourd, peach, ebony, strawberry, tomatoes, cucumber, mung bean and so on.
- Q: Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference
- There is no essential difference, the measurement method is different, so the result is different, the former is the burning method, which is the chemical method or instrument method
- Q: Milk food rich in nutrition, in addition to containing a variety of inorganic salts which also contain three types of organic energy can be organic
- Fat Glucose Protein
- Q: What is the composition of inorganic salts?
- Most of the inorganic salts in the cell are present in the form of ions
- Q: How too much to eat too much inorganic salt
- Eat more inorganic salt, human body cells will be dehydrated, you will feel thirsty; if too much will be serious consequences, as if no one has done, after all, very difficult to eat.
- Q: How to isolate the effects of inorganic salts on enzyme solubility
- The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.
- Q: What foods contain zinc-containing inorganic salts
- No. 3: mud clam [blood clam, bears clam] (11.59 / 30g / 100g)
- Q: What are the nutritional requirements for bacterial growth?
- The nutritional conditions required for bacterial growth generally include water, carbon, nitrogen, inorganic and growth factors
