Product Description:

This product is lumpy substance, its surface is a little deep gray, has slight nasty smell. It can produce acetylene gas when met water, it can burn when meets fire. The acetylene gas mix with air will form explosive gas (explosive range of acetylene gas in the air is 2.3% - 81%).

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:What is the difference between "organic salt" and "inorganic salt"?
Inorganic salts are inorganic acids (hydrochloric acid, sulfuric acid, nitric acid) with alkali generated by the reaction of the salt is called inorganic salts. Inorganic salts are salts that do not contain carbon, and organic salts are carbon-containing but do not include carbonates.
Q:How to isolate the effects of inorganic salts on enzyme solubility
The raw materials of cotton stalk were pretreated with inorganic salt to dissolve part of lignin and hemicellulose, so as to improve the enzymatic hydrolysis efficiency. Sulfuric acid, sulfuric acid and sulfuric acid were used to pretreat the cotton stalk. The solid solution was separated and the lignin removal rate and the elution rate of the pentosan were determined. The solid phase was hydrolyzed at 50 ℃. Enzyme hydrolysis conversion rate; the process of glucose, pentosan, lignin for material accounting.
Q:Relation between salt concentration and amount of drops of saltwater on a penny?
The source below says inorganic salts increase surface tension. In the present case increasing the concentration of salt (and so increasing the surface tension) would result in an increase in the number of drops being held on the surface of the penny.
Q:The application of various inorganic salts in the human body?
All tissues of the human body contain strontium, is also the main component of bone and teeth, mainly gathered in the ossification of the place, can be strong bones.
Q:Cells in the water, inorganic salts, protein, lipid
Water is a mixture
Q:Why can quaternary ammonium salts catalyze the heterogeneous reaction between water-soluble inorganic salts and organic compounds
Quaternary ammonium salts have the characteristics of surfactants, with the water phase of the nucleophile in the composition of the ion pair, into the organic phase, thereby promoting the heterogeneous reaction faster 6224
Q:What is the relationship between electronegativity and the solubility of a inorganic salts?
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:Sodiumcorbonate is inorganic salt , why it is not organic substance even it contains carbon?
Organic molecules have carbon to carbon bonds. EDIT: I wonder why I got a thumb down for stating the definition of an organic molecule? Yahoo answers is a weird place. If there's only one carbon atom in a molecule its not an organic molecule, because there can be no C-C bonds...
Q:Now need to determine the freezing point of inorganic salt solution, what kind of freezing point instrument is more accurate?
Because a large branch of antifreeze is with inorganic salt solution.
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.
