- Q: What is white alkali?
- Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. Chemical purity of more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to the salt, does not belong to the base. International trade, also known as soda or alkaline ash. It is an important organic chemical raw materials, mainly for the production of flat glass, glass products and ceramic glaze. But also widely used in life washing, acid and food processing.
- Q: What is the difference between baking base and common base?
- The main content is not the same
- 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?
- What to eat is more harmful. So you can add the same time while paying attention to the diversity of the diet.
- Q: Is the base and baking soda the same substance?
- Alkali is sodium carbonate, is granular, a bit like white sugar, baking soda is sodium bicarbonate, powder
- Q: Alkali soda water
- In 1772, Joseph Plistree published a book, "Combination of Water and Gas," describing the drop of sulfuric acid on chalk, releasing carbon dioxide and encouraging people to collect gas with a bowl full of water. In 1771, the Swedish chemist Luben Bergman independently invented a manufacturing process similar to that of Joseph Plistry's discovery of carbonated water. But less successful, he managed to produce natural bubbling spring water, then think that bubbling spring is good for health. Now, carbonated water is made by pressurized carbon dioxide through water. The pressure of the pressure is stronger than the standard atmospheric pressure, so that it increases the solubility, so that carbon dioxide into the. When the bottle is opened, the pressure is released, the gas forms a bubble out, thus forming a unique bubble. The best known for carbonated water is the advantage of removing stains, such as coffee stains in coffee cups, or silver stains. It is said that the wine stains can be mixed with salt, and then add a lot of carbonic acid to remove. Carbonated water is available at the grocery store and is also very simple. To the supermarket condiment counter bought to eat soda powder. Then prepare a bottle of mineral water. Will be a drink of water cups, put a spoonful of soda powder, how much soda powder can be based on personal taste to set. If put more, too salty, some people can not stand, put less. And then filled with mineral water, pay attention to the water must be cool. Now the living standard is good, every day big fish and meat eat, the body eat into acidic, drink soda can be neutralized in the body acid and alkali balance, good for health. Drink once or twice a week, stick to it, the body will feel particularly cool.
- Q: What is the use of alkali?
- From acid and alkali combined effect
- Q: That day, I put the alum in the water, and then I smell the gas, I would like to know the alkali is not harmful to people, right?
- Alcohol can release corn is not easy to release niacin, so long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin disease;
- Q: What are the characteristics of the composition of the base?
- Metal ions and hydroxide ions
- Q: What is the harm to the human body?
- Should be appropriate. Alkali, destruction of vitamins, but also a combination of some toxins, if too much intake of alkaline food, will be harmful to the body, easy to damage the absorption of vitamins, sepsis patients, is not conducive to good health!
