- 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: How does the edible base use?
- Alcohol is not a commonly used condiment, it is just a food loose agent and meat tenderener, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use can bring excellent food The color, smell, taste, shape, to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread and so on.
- Q: Alkaline pool can breed what
- In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.
- Q: What is the important character of Chinese made alkali?
- (1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.

- Q: Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?
- Simply said, harmful, will damage the body's internal and alkali balance, easy to get sick.
- Q: How to see the whole bread of the alkali alkali small
- Sniffing Such as the smell of the dough, indicating that the alkali is placed properly. (4) catch. Hand dough, such as dough sinking, inelastic, that the alkali put more; if not sticky, nor sink, and there is a certain flexibility, that alkali is just right. (5) taste. Will be rubbing the base of the dough to pull a little bit into the mouth taste, if the sour that alkali less; if the alkali astringent taste, that the alkali put more; if you feel sweet, that is, alkali is appropriate The
- Q: What is the harm to the human body?
- The disadvantage of soda ash is the vitamin B1, B2 and vitamin C in food have a strong destructive effect, and will affect the body of certain minerals absorption and utilization, and therefore can not be abused.
- Q: What is alkali?
- What is the alkali is the ionic compound, the ionization of the anion is hydroxide (OH-), in fact, the oxygen ion acid root (which can compare sulfur and sulfur), and the anion contains only hydroxide. (Such as LiOH, NaOH, NH3 · H2O) soluble in water, alkaline earth metal ions formed in the periodic table from top to bottom gradually soluble [Be (OH) 2, the alkali metal ions or alkali ions, Mg (OH) 2 is insoluble, Ca (OH) 2, Sr (OH) 2 is slightly soluble, and Ba (OH) 2, Ra (OH) 2 is easily soluble, and other bases are in addition to TlOH and Tl (OH) Is difficult to dissolve alkali and acid metathesis reaction is also known as neutralization reaction, that is, H + + OH- == H2O
