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: The stronger the transpiration is, the faster the absorption rate of inorganic salts and water is: wrong. Can only promote the transport up! Can not promote absorption.

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: What is the inorganic salt: The main sources of various inorganic salts and the lack of the main performance (1) sodium sodium is the main ingredient of salt.China's nutrition society recommended adults over 18 years of age sodium intake of 2.2 grams per day, the elderly should take light food Sodium is commonly found in a variety of foods. The main sources of sodium are sodium, soy sauce, pickled foods, smoked foods, salty foods, etc. (2 Calcium is an important part of bone. Disease, osteoporosis, etc .. China Nutrition Society recommended adults aged 18-50 adult calcium intake of 800 mg per day; 50 years of age in the elderly 1000 mg.General calcium-rich foods are milk, yogurt, Oatmeal, sea cucumber, shrimp, wheat, soybean meal, soy products, lily, etc. (3) magnesium is the necessary elements to maintain the structure and function of bone cells.Magnesium deficiency can lead to nervous tension, emotional instability, muscle tremor and so on. (4) Phosphorus is an important part of the composition of bones and teeth. (4) Phosphorus is an important component of bone and teeth. (4) Phosphorus is an important component of bone and teeth. Severe phosphorus deficiency can lead to anorexia, anemia, etc. China Nutrition Society recommended adults over 18 years of age the appropriate intake of phosphorus is 700 mg. Common phosphorus-containing foods are lean meat, eggs, milk, animal offal, kelp, Nuts, coarse grains. (5) Iron is the most content of trace elements in the human body, iron and the human body's life and its health are closely related to iron deficiency will lead to iron deficiency anemia, immunity decreased. China Nutrition Society recommended 50 years old More than men's or women's iron daily intake of 715 mg. Common iron-rich foods are animal liver, kidney, caviar, lean meat, potatoes, wheat bran.

Q: are there any other foods than water and salt that have an abiotic origin (lifeless, inorganic)?: water and salt aren't foods. There is no caloric value in them, so they cannot be foods. We live on earth. All foods have an organic origin.

Q: Why is the residue after burning known as coarse ash? And inorganic salt content What is the difference: GB / T5009.4-2003 "Determination of ash in food" (a) the principle of a certain amount of samples after carbonization into the high temperature furnace burning, the organic matter is oxidized decomposition to carbon dioxide, nitrogen oxides and Water and other forms of escape, and inorganic substances to sulfate, phosphate, carbonate, chloride and other inorganic salts and metal oxide in the form of residual

Q: Organic chemistry extraction lab. If the KBr wasn&#39;t there I would just add HCl to protonate the NH2, but I&#39;m not sure if that will affect the KBr or the carbon chain. Both of these are in an aqueous phase.: The amine will certainly coordinate to K+, but the interaction is not very strong and hydrogen bonding from water will compete efficiently. Also, if your amine is soluble in water, you are not going to be able to isolate it by turning it into the corresponding ammonium salt.

Q: Why is the inorganic salt left after the burning of the food: Food contains protein, fat, inorganic salts and water and other substances in the process of combustion in addition to inorganic salts and the rest of the water are burned, and water in the combustion process evaporates. So take the only inorganic salt.

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.: I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.

Q: Inorganic salt is not salty: HCl (hydrochloric acid) dilute: more acid, feeling slippery mouth, the typical vomit feeling, slightly spicy. Concentration: extreme acid, spit after the bitter taste, and then the whole mouth cold, 10 minutes later improved.

Q: Please tell in your own language how water and inorganic salts are transported from the soil to the leaves.: The water and inorganic salts in the soil are absorbed through the root of the root of the root of the root of the root of the root, due to root pressure by the body of the fiber duct system to the plant roots, stems, branches, leaves, flowers, fruit parts Of the cells in the supply of nutrients.
