Q:The commonality of the base

alkaline solution can react with salt, generate new alkali and new salt

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: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

Q:What is alkali active aggregate?

In the construction process sometimes encounter the following questions: What is the alkali active aggregate? How does it determine that the aggregate is an alkali-active aggregate? Before answering this question, let's say what is the alkali-aggregate reaction. The alkali-aggregate reaction refers to the soluble alkali (K) in the cement, admixture, admixture or mixed water *, Na *) is dissolved in the concrete void fluid and reacts with the active ingredient (such as SiO2) with the alkali in the aggregate after the coagulation and hardening of the concrete, resulting in alkali-containing gel, water swelling, Internal stress and cracking. It can make a serious decline in the durability of concrete. It is difficult to prevent its development, it is difficult to repair.

Q:Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?

Hair thicken

Q:What is white alkali?

White alkali, base alkali is sodium carbonate, is a hydrolysis of alkaline water content of crystalline water carbonate, chemical composition of Na2CO3. Baking soda, also known as sodium bicarbonate, acid sodium carbonate, that is, NaHCO3, is a kind of salty white alkaline drugs. In addition to diet, but also in the medical field has a wide range of applications.

Q:What is the big base?

Large alkali is the main component of sodium carbonate.

Q:And how to do the big face ah?

In fact, the biggest drawback of alkali is the steaming steamed bread turned yellow does not look good, but the big baked bread is very delicious ah ~ I feel better than the normal bread ~ ~ I think their family to eat, but also eat only The most important

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:Alkali soda water

Soda water is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical disinfectant, drinking and neutralizing the body's acid-base balance, changing the acidic constitution. Most of the soda water sold on the market is a synthetic carbonated beverage that is compressed into purified water and added sweeteners and fragrances. Soda water is a carbonated beverage, is pressed into purified drinking water into carbon dioxide, and add sweeteners and spices. He is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical sterilization, oral administration can be integrated within the body's acid-base balance, change the acidic body. Sodium bicarbonate is what we say baking soda molecular formula NaHCO3 is usually said that the surface screwdriver, but this is not directly joined the surface screwdriver, the market selling soda water is mostly in the purified drinking water into the carbon dioxide, and add Sweeteners and fragrances of synthetic synthetic carbonated beverages. Baking soda: NA2CO3 soda: NAHCO3, weak base. Medical topical disinfection can be sterilization, oral administration can cure too much acid. Soda water is actually carbonated water Well, Coke, whiskey what is inside. Pure soda water also has, usually the equipment, supermarkets have to sell. Can be used for cocktails. Can go to the pharmacy to buy small soda tablets with warm water to the system, but the concentration is not good to master.
