Cautions during transportion:

The packing must be kept in good condition and the goods should be stored in a dry,cool and ventilated place.It should be separate from the cargo can burn and acid.It should avoid meeting water and moisture.It should give off the acetylene in iron drum before storing in warehouse. Rolling drums,heavy putting down and colliding are not allowed to avoid the spark leads to explosion.

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:What is the time when the maximum number of inorganic salts is needed
Potassium is ion-soluble in plant juice, and its main function is related to the metabolism of plants.
Q:Is all the inorganic salts in the body related to life activities?
Sugar is the most important material for the human body, all the activities of the human body, including learning, walking, digestion and breathing, etc., which are the most important substances in the human body. Consumption of energy (about 70%) mainly from the carbohydrates, fat is the body of the energy material, the protein is the basic material of human cells, but also to provide energy, vitamins are neither the main raw material of the organization, nor the supply of energy Material, but it has an important role in the life activities of the human body; inorganic salts constitute an important raw material of human tissue, water is the main component of cells. Which protein, sugar, fat, vitamins can burn for organic matter, and water, inorganic salts can not burn as inorganic.
Q:Chemistry help! physical and chemical properties of salt and sugar!?
I believe it's Physical, most of the times such changes are physical, melting point, sublimation, evaporation, etc.
Q:What is the risk of low inorganic salt?
Iodine content in the human body is much lower than 1/10000  is a trace element. Function  iodine in the human body to participate in the formation of thyroid. In the protein, fat, sugar metabolism  promote bio-oxidation and coordination of oxidation of phosphoric acid process, adjust the energy conversion. Promote the metabolism of sugar and fat, regulate the water and salt metabolism in the organization, promote the absorption and utilization of vitamins, activate many important enzymes, promote growth and development. Lack of disease  adult iodine deficiency can cause goiter ⑴ fetal and neonatal iodine deficiency can cause minor illnesses. Typical cases  endemic goiter and local minor illnesses. Excessive symptoms  iodine goiter, iodine thyrotoxicosis. Supply  Adult 150ug  Pregnant woman 175ug 206 Emulsifier 200ug. Food source 海 seafood seaweed, seaweed, fresh fish, clam dry, clam dry, scallops, mussels hai sea cucumber, jellyfish, lobster, etc.
Q:is sugar and salt organic or inorganic?
Healthy compounds have carbon in them at the same time inorganic compounds should not have carbon. For example, sugar (C6H12O6) has six carbons, and is for this reason an organic compound. Water then again (H2O) does now not have a carbon in it and is an inorganic compound.
Q:In order to prove that magnesium is an essential salt for soybean life
Biological control experiments were the only variable experiments. The question that is being explored is the variable, and the other quantities are the same. In a different amount (conditions) the same circumstances to modify a data variable in order to get the data variables on the experimental changes in the law. In order to prove that magnesium is essential for the life of soybeans, the variable is the presence or absence of magnesium. Can be designed as a magnesium-containing culture medium and magnesium-free culture medium. The other amount of the same as the amount of culture medium, soybean seedling growth status, the same number, while placed in the same place, etc., to ensure that only one variable that is the presence of magnesium.
Q:What are the nutritional requirements for bacterial growth?
For inorganic salts: bacteria need a variety of inorganic salts to provide a variety of elements of bacterial growth, which requires the concentration of 10.3 ~ 10.4mol / L elements for the common elements, the need for concentration in the
Q:What are these salts used for please?
HI I'M PNT. LITHIUM SULFATE is a white inorganic salt with the formula Li2SO4. It is used to treat bipolar disorder. It is soluble in water, though it does not follow the usual trend of solubility versus temperature — its solubility in water decreases with increasing temperature . This property is shared with few inorganic compounds, such as the lanthanoid sulfates. Lithium sulfate crystals, being piezoelectric, are also used in ultrasound-type non-destructive testing because they are very efficient sound generators. However they do suffer in this application because of their water solubility. ZINC NITRATE: Zinc nitrate (Zn(NO3)2) is a chemical compound used as a mordant in dyeing. It is also a source of zinc ions for chemistry. An example reaction gives a precipitate of zinc carbonate:Zn(NO3)2 + Na2CO3 → ZnCO3 + 2 NaNO3. Conditions/substances to avoid are: reducing agents, organic materials, metal powders, heat and flame, cyanides, sodium hypophosphite, tin(IV) chloride, phosphorus, thiocyanates, carbon, and sulfur. Its Relative Molecular Mass is 189. SODIUM PHOSPHATE: Sodium phosphate are forms of phosphorus, which is a naturally occurring substance that is important in every cell in the body. Sodium phosphate is used to treat constipation and to clean the bowel before surgery, x-rays, endoscopy, or other intestinal procedures. Sodium phosphate enemas are also used for general care after surgery and to help relieve impacted bowels. Sodium phosphate may also be used for other purposes not listed in this medication guide REGARDS, PNT.
