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: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:in the ocean: Salts are the result of the association of cations and anions. Cations are usually metals like Calcium, Sodium, Potassium anions are ususally sulfates, phosphates, carbonates...... calcium carbonate and calcium phosphate are useful in making bone. Potassium Chloride is important in heart beat regulation Sodium Chloride is important in maintaining blood pressure. Carbonate is important in blood chemistry and the transfer of energy within a cell. all these salts are found in abundance in the ocean. If you follow evolution, those salts in the ocean have given rise to our own blood chemistry and organic health.

Q:The difference between the ignition of inorganic salts and organic matter: Calcium is an important part of bones. Calcium deficiency can lead to osteomalacia, osteoporosis and so on. China Nutrition Society recommended 18-50 adult calcium intake of the appropriate daily intake of 800 mg; 50 years old after the elderly taste 1000 mg. Common calcium-rich foods are milk, yogurt, oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily and so on.

Q:Several inorganic salts are lacking in symptoms and food sources: Phosphorus-containing inorganic salts of food sources: seafood and so on

Q:Why vegetables and fruits contain rich inorganic salts: Because they are plants! From the biological point of view, they are the nature of the organic matter into inorganic salt carrier

Q:Are plants absorbing water and inorganic salts only through root tip or wrong? The: This is wrong.

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:What foods contain inorganic salts?: Most of the food contains inorganic salts, the so-called inorganic salts, also known as minerals or ash. Minerals are naturally occurring compounds or natural elements in the crust. There are about 50 kinds of minerals in the human body, although they in the human body only 4% of body weight, but it is an essential part of the organism. Kelp, jellyfish, seaweed, moss; bones, soy products, lean meat, animal liver, brown rice and so on.

Q:What is the disease of inorganic salt crystals?: Drink less, the urine will be reduced, the urine of the inorganic salt concentration will be high, the discharge of urine encountered outside the cold air, will immediately cool, urine inorganic salts to precipitate down, so that urine Into the lime watery white turbid liquid. Check this urine, the urine heated to a certain temperature will make it clear; also due to temporary urine alkalization caused by white turbid urine, such as taking alkaline drugs or After a lot of alkaline food, or eat can make the inorganic salt in the urine of the increase in the content of food, fruit, vegetables, there will be white urine.

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
