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) 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?: Usually solubility will increase with increasing temperature but there are a significant number of exceptions which show the opposite.

Q: Are there any differences between minerals and inorganic salts?: There are differences, some minerals exist in organic matter, and some minerals are inorganic salts. Inorganic salts are inorganic.

Q: What are the physiological functions of inorganic salts: Maintain the life of cells and organisms

Q: Inorganic salt function: Although inorganic salts in the cell content is relatively small, but there are many important role.

Q: A solution is known to contain an inorganic salt of one of the following elements. The solution is colorless. The solution contains a salt ofa. Cub. Mnc. Fed. Nie. Zn: Mn or Zn. Both MnSO4 and ZnSO4 solutions are water-white. KMnO4 is purple. But you did not stipulate.

Q: The importance of water and inorganic salts to life is reflected in those aspects: The role of water: 1. as a good solvent to dissolve nutrients and metabolic wastes, involved in the metabolism of body fluids. 2. To provide the water environment required for cell survival. 3. As some of the reaction of raw materials, such as photosynthesis, protein hydrolysis . 4. Is divided into the combination of water and free water constitute the two major forms of cells. 5. Plant to help carry out the role of transpiration heat

Q: Think about the physical and chemical properties of salt and sugar. What properties do these substances have in common? Describe which properties you could use to distinguish between them. What properties and units would you use to describe their physical and chemical characteristics? List as many as you can.: Salt: inorganic, ionic bond, soluble in water (ionizes); forms a crystal lattice structure as a solid. Sugar: organic compound, mostly covalent bonds, also soluble in water but does not ionize, can be burned, tastes good (just kidding).

Q: Inorganic salt through what way into the human body: The inorganic salt enters the human body through active transport.

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.

Q: as a example potesium,sodium,magnees,calcium: The sodium-potassium pump is most important in controlling the working of neurotransmitters. Calcium ion is also generated in voltage gated Ca++ channel, and Magnesium is necessary for metabolic functions. But Sodium is one of the most important inorganic component in our body. Of course Potassium is also as important. But, if you have ever seen the back of all food products there is a special part showing amount of Sodium in it...even Snacks.. :)
