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:Would you like some rice when you cooked rice or millet gruel?
Sometimes some people in the cooking boiled rice gruel, grasp some of the alkali on the porridge, the big canteen chef especially like to do so. On the one hand figure cooked fast, on the other hand add alkali after cooking porridge more sticky delicious, taste and good.

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 alkali active aggregate?
The active aggregate is the active mineral fine admixture can promote the cement hydration product further transformation, improve the hardened concrete pore structure, improve the concrete compact performance
Q:What is the use of alkali?
Can be removed in the clothes when the clothes on the oil, you can neutralize the sour in the face, you can make the porridge easier to boil.
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:And how to do the big face ah?
Add some vinegar for some time. You can use the yeast hair, so that will not produce such a problem.

Q:The commonality of the base
alkaline solution can react with salt, generate new alkali and new salt
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.
