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

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 foods contain zinc-containing inorganic salts
- No. 4: Chibi (11.58 / 34g / 100g)
- Q: How can experiments prove that there are inorganic salts in the leaves of plants
- The experimental leaves used to dry, crushed into powder or sintered ash, and then the analysis of mineral elements, we can learn.
- Q: how come a penny can hold more drops of the salt water solution than just plain tap water from your faucet?
- It okorder /
- Q: Are the inorganic salts mineral and they are soluble in water?
- Generally speaking, inorganic salts, including minerals, inorganic salts are not minerals. Some inorganic salts can be soluble in water and some can not, the vast majority of minerals do not dissolve in water, otherwise the rain on the rocks are not dissolved Is it gone?
- Q: List the major electrolytes released by inorganic salts when placed in water and explain how these electrolytes are needed for metabolic reactions.
- Which "inorganic salts" are you talking about? There are hundreds!
- Q: What is the relationship of electronegativity and the solubility of a inorganic salts?Does the solubility increase when electronegativity decreases or vice-versa? or neither...
- The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
- Q: How to extract inorganic salts in soil?
- Find a piece of mud, with water, filter out the permeate, filter with filter paper. The liquid was placed in a beaker and dried to obtain white crystals
- Q: Is the inorganic salt the same as the saline?
- Inorganic salts are inorganic compounds in the tears, originally called minerals. A large number of elements are calcium Ca, phosphorus P, potassium Ka, sulfur S, sodium Na, chlorine Cl, magnesium Mg, trace elements iron, zinc, selenium, molybdenum, fluorine , Chromium, cobalt, iodine and the like.
- Q: Is iodized salt inorganic or organic?
- A salt, by definition, is the product of a reaction between an acid & a Base. As Imrul has said, if it has a carbon, it's Organic. The Iodine is from the base, so the other part would have to be from the acid, a metallic one at that. As there's no more clear informatiom, you must take it as Inorganic.
