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 effect of inorganic salt medium and the difference with enrichment medium
- The landlord said the basic nutrient base? That is based on the inorganic salt with carbon source and energy sources, such as beef extract, peptone, etc., the basic nutrients can provide the necessary cells to grow cells.
- Q: How much of the body's inorganic salts account for the weight of the body?
- The inorganic salts in the human body account for about 5%
- Q: Determination of the existence of inorganic salts in the soil, in the filter, should pay attention to the matter
- A sticker: filter paper close to the funnel wall, so that no bubbles.
- Q: General identification method of inorganic salts
- Take platinum wire, with hydrochloric acid wet, dipped in the test sample, burning in the colorless flame, the flame that was purple. But a small amount of sodium mixed, must be separated from the blue glass perspective can be identified. 2K ++ [PtCI6] 2- → K2PtCI6
- Q: Is calcium carbide inactive?
- Calcium carbide, the chemical formula for the CaC2, not inorganic salts. Salt refers to the metal ions and acid ions of the compound, calcium carbide does not have the corresponding acid.
- Q: Please help me!
- This Site Might Help You. RE: Why is sodium chloride(salt) an inorganic compound? Please help me!
- Q: is table salt organic or inorganic, why?
- Inorganic - NaCl - no complex carbon compounds.
- Q: How to extract inorganic salts in soil?
- Find a piece of mud, with water, filter out the permeate, filter with filter paper. The liquid was placed in a beaker and dried to obtain white crystals
- Q: Effects of Minerals on Plants
- Root absorption of mineral elements is based on cell uptake. But the root of the absorption of mineral elements has its own characteristics. First, the roots of salt and water relative absorption. As the root of the salt and water absorption mechanism is different, the absorption is disproportionate. The second is that the root system is selective for the absorption of mineral elements. That is, some of the absorption of some ions, while the absorption of some ions with little or no absorption. The third is that single salt poison and ion confrontation. The general cationic toxic effect is obvious, the anion toxic effect is not obvious. In the single salt solution if adding a small amount of other valence of different metal ions in the salt, single salt poisoning phenomenon will be reduced or disappeared. This effect of ions is called ion confrontation. Generally in the periodic table of different groups of metal elements between the ions will have a confrontation. Plants as long as a certain concentration, a certain proportion of a variety of salt mixture in order to normal growth, this solution is called the balance solution. In the fertilization should be very careful.
- 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?
- Inorganic salts are inorganic compounds in the salt, formerly known as minerals, the body has found more than 20 species, including constant elements of iron, zinc, selenium, molybdenum, chromium, cobalt, iodine 8. If you pay attention to diet diversification, eat Animal fat, eat brown rice, corn and other coarse grains, do not eat too much refined flour, can make the body of inorganic salt to maintain the normal level should be.
