- Q:Do you eat too much alkali to harm your body?
- Excessive intake of alkali hazards: The disadvantage of edible alkali is the food in the vitamin B1, B2 and vitamin C has a strong destructive effect, and will affect the body of certain minerals absorption and utilization, so do not overuse.
- Q:What is the name of the alkali?
- Our chemist Hou Diban, invented a [Hou Debang base of the law]. A sensation of the world. This is our pride.
- 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?
- In the process of hair will have a microbial acid, dough after the initiation of acid, must be added alkali, in order to produce a delicious pasta;
- Q:How to go to the base of the teapot

- Q:What is the difference between baking base and common base?
- The aqueous solution of the two is worse. Do German or use the baking base, I have tried, not only different colors, taste and taste are also significantly different.
- 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: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 the important character of Chinese made alkali?
- In 1862, the Belgian people Solvay (Ernest Solvay 1838-1922) invented the salt, ammonia, carbon dioxide as raw material for the production of sodium carbonate "Solvay alkali method" (also known as the ammonia method). Since then, Britain, France, Germany, the United States and other countries have established a large-scale production of soda ash plant, and organized the Saul Wei Association, members of the country outside the implementation of technical blockade.
- Q:What to do with the wall
- Wall latex paint suggest you re-done. Especially to make the primer
- Q:How does the edible base use?
- (Sodium carbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is made from soda ash solution or crystal absorption of carbon dioxide after the finished product, both There is no difference between the system. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water.
