Q:And how to do the big face ah?
Steamed bread in the time, the hair surface of the alkali will really lead to steamed yellow, there will be a burst of relatively strong alkali taste, so that people will not have appetite. It can not be so no matter what, or steamed steamed bread on the waste. Hair alkali, then, you can steamed bread in the water, add some vinegar, and then into the pot steamed After a while miracle will be produced, and after about 15 minutes, you will see, just still yellow buns, has instantly turned into white, and there is no sense of 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 the important character of Chinese made alkali?
Hou Diping famous chemist, "Hausdorck Alchemy" founder. He has worked for China's chemical industry and has been known for his life in the world. Sodium carbonate is used extensively. Although people have been from the saline soil and salt lake in the sodium carbonate, but still can not meet the needs of industrial production.
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:What is the big base?
Large alkali is the main component of sodium carbonate.
Q:What is the role of alkali in the surface
Nutritional analysis: 1. In the process of hair will have a microbial acid, dough after the initiation of acid, must be added to the alkali (carbonate) to acid off in order to produce a delicious pasta; And dark green vegetables due to the excessive spraying of pesticides and organic acids or sulfide, which can keep the original color of vegetables and pesticides to remove the pollution of vegetables; 3. Alkali has a strong role in degreasing, can Remove the oil on the dry goods on the raw material of excess oil; 4. Alcohol can release corn is not easy to release nicotinic acid, so that long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin; The disadvantage is that the food in the vitamin b1, b2 and vitamin c 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
Q:What is white alkali?
White alkali is dough (soda, soda ash), scientific name sodium carbonate, chemical formula Na2CO3.
Q:What is called alkali recovery
Alkali recovery treatment method is to solve the problem of black liquor is more effective way, through the black liquor extraction, evaporation, burning, causticization of the four main sections, black liquor can be SS, COD, BOD together and completely removed, and recyclable Alkali, resulting in secondary steam (energy). However, the alkali recovery system has high technical requirements and high investment in equipment. Since the small and medium sized paper mills are generally unable to bear the high cost of building the alkali recovery system, the alkali recovery system is only mainly used in large paper mills. In addition, the straw pulp produced white mud in the high silicon content, easy to burn back into lime, white mud may cause secondary pollution.
Q:What are the characteristics of the composition of the base?
The anions obtained when ionizing are all OH- are bases; alkali: OH- and metal ions (or NH4).
