- Q: Who can tell me what is plant alkalinity?
- (Sodium bicarbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is a solution of soda ash or crystal absorption after the carbon dioxide Of the finished product, the two are essentially no difference. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water. 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: Why does not the base noodles rub?
- May add too much water. Noodle black is caused by alkali, you can use the source of gluten instead of edible alkali.
- Q: How does the edible base use?
- Avoid the food on the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated several times the raw material can be;
- Q: What is alkali active aggregate?
- Aggregate in the active SiO2 is too high, such as chalcedony, agate, scales quartz, square quartz and so on.
- Q: What is called alkali recovery
- Extraction equipment extraction status is good or bad, largely depends on the extraction of equipment. Different pulp, there are different equipment selection. At present the factory application is the most four series of drum-type vacuum washer. Its technology is mature, easy to operate, from the pulp into the pulp, the basic completion of the separation of pulp and black liquor, the extraction rate is also high. Pulp washing degree and the production of black liquor indicators are basically able to meet the choice of more manufacturers. The disadvantage is the big investment, power consumption.
- Q: What is the name of the alkali?
- You say is probably the daily life of the [base] it?
- Q: How to go to the base of the teapot
- Vinegar, or toothpaste, you try
- 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 role of alkali in the surface
- (Sodium bicarbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is a solution of soda ash or crystal after the absorption of carbon dioxide after the finished product , The two are essentially different.Therefore, the consumption of alkali in some places also known as baking soda (powder). Edible alkali was solid state, round, color white, soluble in water. Alkaline is not a common Seasoning, it is just a food loose agent and meat tenderizer, can make dry goods raw materials quickly rise, soften the fiber, remove the dough's sour taste, the appropriate use for food can bring excellent color, Shape to enhance people's appetite. Alkaline used in a large number of food processing such as noodles, bread, bread, etc.
- 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
