Q:What is alkali sand
Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.
Q:What is called alkali recovery
Alkali recovery treatment method is to solve the problem of black liquor is more effective way, through the black liquor extraction, evaporation, burning, causticization of the four main sections, black liquor can be SS, COD, BOD together and completely removed, and recyclable Alkali, resulting in secondary steam (energy). However, the alkali recovery system has high technical requirements and high investment in equipment. Since the small and medium sized paper mills are generally unable to bear the high cost of building the alkali recovery system, the alkali recovery system is only mainly used in large paper mills. In addition, the straw pulp produced white mud in the high silicon content, easy to burn back into lime, white mud may cause secondary pollution.
Q:What inorganic salts are needed for seeds?
Phosphate, nitrogen, magnesium, calcium, iron, copper, and boric acid
Q:Is bromine an inorganic salt?
Bromine is an inorganic element & forms salts for e.g.with Sodium to form Sodium bromide. It's a highly corrosive liquid & dangerous to handle. It's made from mother liquor - liquid got after extraction of solar salt from highly cocentrated brine.
Q:Does the lack of inorganic salts cause convulsions?
The lack of important substances in the salt body is indeed the use of salt to protect the health of important substances than the calcium and phosphorus main body bone calcium blood coagulation muscle contraction and nerve cell regulation very important phosphorus calcium with the same function of food are preserved phosphorus body lack of calcium muscle spasms Can be rash dyspnea gastrointestinal paralysis and other body no phosphorus calcium calcium phosphate can be used to make bone calcium and phosphorus with a reasonable reason to play its role in the use of salt my body's non-essential body about 50 grams of salt according to 0 --- 2 5 grams To follow the excreta outside the body need to be added or otherwise the body of the production capacity of the body is extremely lack of salt can be fainting disease to speed up or even cause muscle weakness in the iron content and its role is not important in vivo iron deficiency anemia and other iron deficiency
Q:Lack of calcium, phosphorus, iron, zinc inorganic salt should eat what?
Drinking milk is more appropriate to do a proper practice, the milk is rich in calcium, phosphorus, iron, and zinc. There is a food that is eaten inside the sea, the sea of food is basically the content of inorganic salts are relatively high.
Q:Elementary is a few years of course
Elementary is the first three years of chemistry
Q:Octopus why the lack of boron-containing inorganic salts can cause rape to flow only without fruit
Boron has a great influence on the reproductive process of plants, which can accelerate pollen differentiation and pollen tube elongation. In the absence of boron, pollen tube germination is affected, poor fertilization, which leads to the formation of seeds affected, the reduction of growth hormone produced by the reduction of growth hormone will affect the formation of fruit.
Q:What is HD?
Elemental matter is composed of the same element of pure matter. HD is a pure chemical composed of H2 and D2 chemical reaction, and H and D are isotopes, so meet the conditions of elemental.
Q:Where can I find a list of all inorganic salts?
That list is near endless. There are countless inorganic cations and organic groups that can combine with these ions. Pretty much every metallic element in the periodic table will form cations with bromide and chloride. Not sure about phosphate, but most metals will bind with it. Carbonate will be trickier, as some ions are too acidic and will decompose the carbonate (iron(III) is an example, and it will form the oxide instead, liberating CO2 in the process). Aside from simple elemental ions, there are also polyatomic cations (such as ammonium) and lots of complexes that will form compounds with these anions.
