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

1)How many tons does your factory can supply each moth?

30000tons/month

2)How to quarantee the quality of the products?

you can arrange SGS&BV or other quality inspection.

3)How many days you need to pepare the cargo after we made the order?

within 30 days.

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: anybody here knows the difference of organic iron salt (ex. F.gluconate) vs inorganic (ex. F.sulfate)?: It it's organic, then the anion (the negative ion) is the conjugate base of an organic acid. If it's inorganic, then the original acid was inorganic (like H2SO4 making sulphates).

Q: What is an inorganic salt?: Encyclopedia is defined as: inorganic salts that inorganic compounds in the salt

Q: How much of the body's inorganic salts account for the weight of the body?: The inorganic salts in the human body account for about 5%

Q: Advertisements related to inorganic salts -.-,: This is a good new, with a new cover in the cover of high calcium, a top of the past five, high pressure film, fruit flavor, a piece of bang on the fifth floor, not the same time, Feast children! One day one, the effect is good, but also affordable!

Q: Is calcium carbide inactive?: Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.

Q: Why are inorganic sodium salts much better soluble in ethanol than potassium salts?: The reason seems to be : - Ionization potential of pottasium is lower than that of sodium ,thereore potassium salts are more polar as compared to sodium salts; - Potassium being more reactive than the sodium reacts faster withbwater,

Q: is table salt organic or inorganic, why?: if its found in nature its organic if its made by man its synthetic. table salt is found in the ocean so i guess it would be organic.

Q: RO reverse osmosis water machine can remove impurities in the water, that the body will not be due to lack of minerals and malnutrition?: Dr. Henry A. Schroeder, the world's mineral authority, says that the minerals required by the human body are present in the water, meaning nothing more than those that exist in food.

Q: What is the use of inorganic salts in plants? How is it discharged: Plants need inorganic salts, just as people need trace elements, the growth of auxiliary organisms can be through the leaves of the surface of the pores, with the water discharged together

Q: therefore indigestible..that I should look for organic plant based trace mineral compounds..anyone care to comment?: All trace minerals are "inorganic". That's what a mineral is. What the article means is that they are inorganic in the sense that the supplements just have mineral compouds, rather than being derived from a food source. That doesn't make them indigestible, but it can mean they aren't as readily absorbed. Vitamins and minerals are ALWAYS absorbed better when derived from food sources, such as eating a balanced diet, then they are by popping a supplement with a mineral compound in it. But if you need supplements, I don't know if there's such a striking difference between regular mineral supplements or "plant-based" whole food supplements. I don't doubt that whole food plant supplements are probably better, but I don't know that they're better to the degree that it makes the regular supplements "terrible". The best source is STILL diet.
