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: I&#39;m said that with the increase of temperature the inorganic salts will decrease. Will that be correct?: IIRC, it depends on the salt.

Q: Are there any differences between minerals and inorganic salts?: For example, iodine in kelp, calcium lactate in sour milk, etc. These minerals are not inorganic salts.

Q: How to get an inorganic salt: Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.

Q: By balancing the benefits of dietary supplementation with inorganic salts, what are the advantages and disadvantages of taking health care agents?: Diet supplementation of inorganic salt or the nutritional needs of the human body is the normal diet of human absorption, rather than through deliberate conditioning to mobilize the body's ability to absorb (including deliberately balanced diet), that is, add inorganic salt only conventional diet Yes, no other adjustment supplement is its benefit, that is, healthy people do not need to like non-healthy state as a way to seek additional, this is his advantage.

Q: I am an AP biology student testing how magnesium effects the rate of photosynthesis in a plant. However since my class period is only one hour long I highly doubt if i add epsom salt to the soil ( after mixing it with water) i will see an immediate increase in the rate of photosynthesis. So i need to know how long should i wait to test photosynthesis rates after adding an epsom salt solution to the soil of a plant. Or how long does it take for magnesium to be incorporated into a plants rate of photosynthesis. Thanks in Advance!: Magnesium sulfate (or magnesium sulphate) is an inorganic salt (chemical compound) containing magnesium, sulfur and oxygen, with the formula MgSO4. It is often encountered as the heptahydrate sulfate mineral epsomite (MgSO4·7H2O), commonly called Epsom salt, Magnesium is part of the chlorophyll in all green plants and essential for photosynthesis. It also helps activate many plant enzymes needed for growth. Rate of photosynthesis does not depend upon any single factor . so it is futile to expect it should increase after addition of epsom salt to soil in solution form . Because first it should be incorporated in chlorophyll molecule . That depends upon formation of new leaves . Old leaves already have it ( formula of chlrophyll a = C55 H72 O5 N4 mg ) That is the requirement is just one atom per molecule . what to do with excess ? Unless the soil is deficient in Mg . It it useless to add it . soil pH is another factor to be considered = Soil pH (a measure of the acidity or alkalinity of the soil) Soil pH is one of the most important soil properties that affects the availability of nutrients. Macronutrients tend to be less available in soils with low pH. Micronutrients tend to be less available in soils with high pH. www.ncagr /cyber/kidswrld/plan...

Q: After a lot of sweating, the amount of drink with inorganic salt drink right?: It is best to drink this kind of drink, which contains sodium and potassium, and when the body after a lot of exercise will consume a lot of potassium, leaving the body feel weak, this drink can quickly add the body Electrolyte, need to note that before the exercise 1-2 hours, during exercise and after exercise have to drink

Q: As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: According to the study, three essential conditions for determining the essential nutrient elements of the plant are: (1) This element is essential for the vegetative growth and reproductive growth of the plant. When it is completely absent, the plant can not complete its life cycle; The need for such elements is specific, other elements can not replace its role, the lack of plants will be a special lack of symptoms, only to meet this element, the symptoms will be eliminated; ⑧ this element must be in the plant from the body Direct effect, not just to improve the plant growth environment indirect role.

Q: I am 18 years old, test the body of inorganic salt content of 3KG, people say that low. What is the value of this use? How can improve it?: Due to metabolism, every day a certain amount of inorganic salts from a variety of ways excreted, and thus must be supplemented through the diet.Energy metabolism can be analyzed by the blood, hair, urine or tissue to determine the concentration in the human body Inorganic salts are interrelated in the appropriate concentration range beneficial to human and animal and plant health, lack or too much can cause disease, and disease and affect its metabolism, often increase its consumption in China calcium, iron and iodine The lack of more common selenium, fluoride and other geochemical environment with the different, both the lack of disease such as Keshan disease and Kashin-Beck disease, teeth, etc., there are too many diseases such as fluoride and selenium poisoning.
