11. Packing
50kg or 100kg iron drum
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: Several kinds of inorganic salt food sources?
- Pepper, bamboo, bamboo, seaweed, lily, nuts, bread, dairy, beans, seaweed, kelp, kelp, Olives, cauliflower, amaranth, shepherd's purse, salted egg, noodles, fermented bean curd, tempeh, spinach, amaranth, spinach, coriander, fruit
- Q: Inorganic salts play an important role in maintaining the life activities of living organisms. It is mainly in the form of living organisms.
- Inorganic salts are mineral nutrients present in the body and in the food. Most inorganic salts in the cells are present in the form of ions, consisting of organic matter and inorganic compounds.
- Q: How to get an inorganic salt
- Inorganic salts are salts of inorganic compounds, formerly known as minerals. Plant growth needs N, P, K three elements and Ca, Zn, B, Mg, S, Fe and other trace elements. Depending on the type and amount of inorganic salts required for plant life, the water and various proportions of inorganic salts are scientifically formulated into plant nutrient solutions. The method of cultivating plants with plant nutrient solution is called soilless cultivation. The inorganic salts used to prepare the nutrient solution are generally not available for extraction, such as potassium nitrate, calcium nitrate, magnesium sulfate, potassium dihydrogen phosphate, copper sulfate, zinc sulfate and the like, and the reagent may be a chemical fertilizer. The purity of the reagent is high and the impurities of the fertilizer are more. If you can not get it, you can use soil leaching solution (fertile soil plus fresh water, the liquid obtained after filtration), which generally contains a variety of inorganic salts.
- Q: For patients with ulcerative colitis, which inorganic salt foods can eat?
- Inorganic salts with water-soluble and can not oxidize the combustion and other properties, plays a role in maintaining the body's acid-base balance and metabolism.
- 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: What is the lack of inorganic salts for children?
- Zinc salts, iron salts and calcium salts
- 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: Why are inorganic sodium salts much better soluble in ethanol than potassium salts?
- The reason seems to be : - Ionization potential of pottasium is lower than that of sodium ,thereore potassium salts are more polar as compared to sodium salts; - Potassium being more reactive than the sodium reacts faster withbwater,
- Q: What is the relationship of electronegativity and the solubility of a inorganic salts?Does the solubility increase when electronegativity decreases or vice-versa? or neither...
- The higher the electronegativity, the stronger the acid would be... Therefore it would be more soluble. take NaCl (common table salt) as an example. The difference between Na's electronegativity and Cl's electronegativity is very high so NaCl is a very soluble salt. The only exception is HF - it is a weak acid - it dissociates very weakly because O-H bonds cannot break H-F bonds which are very strong.
- Q: The addition of inorganic salt viscosity of micelles increased first and then increased again and then reduced, there is no possibility ah? Yes, then what is the reason for the increase ah?
- possible. The inorganic salt is dissolved in water to form positive and negative ions, and the ions of the micelles are extruded to make the solubility smaller and form an increase in the viscosity. With the increase in the amount of inorganic salt, it does not have the ability to dissolve in water, there is no micelles and the molecular state exists in the water, the liquid becomes thin ...
