5.FAQ

1, are you a trade company or factory?

We are a trade company.

2, what is your main product?

My main product is ammonium chloride all grade. We have special advantage in FEED

GRADE.

3, how do you control the quolity?

We do quolity control by the factory testing department. We also can do FDA,BV, SGS or any orther Third-party testing.

Q:Indicating the organic compounds and inorganic salts in the boiling point, melting point and solubility of what is the difference: Organic compounds are mainly covalently bonded, the mutual attraction between molecules is very weak, so its melting point, low boiling point, generally insoluble in water and soluble in organic solvents. Inorganic salts with ionic bonding, positive and negative ions electrostatic attraction is very strong, so the melting point, boiling point is very high, usually insoluble in organic solvents and soluble in water.

Q:Which minerals is richest source of Inorganic Salts ?: Minerals are inorganic salts - eg.potassium nitrate - absorbed by plants from soil - a good source of inorganic nitrogen and potassium.

Q:I am a candidate for this year's Harbin City, Jiqiu the standard answer, tomorrow I will test !!!: It is the life activity of the organism. Such as: magnesium ions are ATPase activator, chloride ion is an activator of saliva enzyme.

Q:As if there are two kinds of nitrogen, phosphorus and potassium, hoping to get answers and explain their respective roles: (N) Nutrition: Nitrogen is necessary for the growth and development of plants. Usually, the total amount of nitrogen in plants is not too high, such as 1.0-2.0% of the whole plant. The plant is a plant with high nitrogen content, and the nitrogen content in the plant leaves is about 3.5-5.0% of its dry weight.The nitrogen is mainly absorbed in the form of ammonium nitrogen and nitrate nitrogen, and some small molecules of organic nitrogen Such as urea can also be absorbed by plants.Now is the main component of protein, accounting for about 16-18% of the protein content in the cytoplasm and the nucleus are containing all the enzymes are also the main body of the protein.In addition, the nucleic acid, Phospholipids, chlorophyll, coenzyme and other compounds contain nitrogen

Q:citrate, What is the rationale for using a medium with this type of composition for the performance of the citrate utilization test?Thank you!: as it has no other sources of nutrition, only citrate metabolizers will be able to grow and thrive on this medium. If your organism grows, you know it is a citrate metabolizer which helps to identify the bacteria.

Q:ATP components are not inorganic salts: Of course not pulling, because ATP is decomposed by glucose to get energy that is ATP and salt and water.

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:What cells produce the collagen and inorganic salts of bone matrix?: Inorganic Salts In Bone

Q:What fruit contains more minerals?: Persimmon contains a lot of carbohydrates, per 100 grams of persimmon containing 10.8 grams, mainly sucrose, glucose and fructose, which is why we feel very sweet persimmon persimmon in the other nutrients are not only contain a small amount of fat , Protein, calcium, phosphorus, iron and vitamin C. In addition, persimmon is rich in pectin, it is a water-soluble dietary fiber, a good laxative effect, for correcting constipation, to maintain normal intestinal flora Growth and so have a good effect.

Q:What are the effects of inorganic salts on plant growth?: In addition to these three types of inorganic salts, plants also require many types of inorganic salts. Among them, the demand for some inorganic salts is very small, but they are in the life of the plant also plays a very important role. For example, the lack of inorganic salts containing Fe, fruit trees will be yellow leaf disease; lack of inorganic salts containing B, rape will be "flowers and not real" (only flowering fruit).
