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

5.FAQ
4, how about your packing?
My main packing is 25kg or 1000kg PP PE or kraft bag , with or withour pallets,with or without anticaking. We also can make packing and shipping mark are your ask, such as 50kg/50bl bag.
5, how long time you can make the shipping?
We can make the shipping within 5-10day after confirm the order.
6, why you buy from me?
We have stable quolity and price, not best quolity and price. It is not true for best quolity and best price. Our factory is manufacture according the BP USP and FCCIV terms. We have in this line for more than 8 years. We are one of the biggest exporter from Qingdao port.
- Q: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is
- wrong. Can only promote the transport up! Can not promote absorption.
- Q: What is inorganic salt
- The distribution of inorganic salts in the body is extremely uneven. For example, calcium and phosphorus are mostly in hard tissue such as bone and teeth, iron is concentrated in red blood cells, iodine is concentrated in the thyroid, barium is concentrated in adipose tissue, cobalt is concentrated in hematopoietic organs, and zinc is concentrated in muscle tissue.
- Q: What do we get from the milk?
- Milk is rich in minerals, calcium, phosphorus, iron, zinc, copper, manganese, molybdenum. The most rare is that milk is the best source of calcium in the human body, and the proportion of calcium and phosphorus is very appropriate, conducive to the absorption of calcium. Species is complex, at least 100 kinds, the main ingredients are water, fat, phospholipids, protein, lactose, inorganic salts
- Q: Why is the inorganic salt left after the burning of the food
- Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.
- Q: What are the important physiological effects of inorganic salts in cells
- Composition of cells in some important compounds,
- Q: Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?
- Organic molecules have carbon to carbon bonds. EDIT: I wonder why I got a thumb down for stating the definition of an organic molecule? Yahoo answers is a weird place. If there's only one carbon atom in a molecule its not an organic molecule, because there can be no C-C bonds...
- Q: Cells in the water, inorganic salts, protein, lipid, carbohydrate and nucleic acid six words how wrong this sentence
- Divided into organic compounds and inorganic compounds are not two categories
- Q: What are the main physiological functions of inorganic salts?
- o maintain the body acid and alkali balance and osmotic pressur
- Q: I am told to find which bottled mineral water brands contain the most mineral salts.But im not sure if the mineral salt here is talking about the common table salt (Sodium Chloride) or the chemical salt (ionic compounds such as sulfate and chloride) or the whole list of dietary minerals (potassium, chlorine, calcium, magnesium, ect.) I normally think it is just the table salt but im afraid I might get wrong. So what is the exact definition?
- Definition Of Mineral
- Q: I need help with this
- anything which contain carbon is organic. so enzyme is the odd one out.
