- Q:The commonality of the base
- Alkaline solution can react with acid and alkali indicator
- 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:Why does not the base noodles rub?
- Yes, you are not practicing
- Q:Do you eat too much alkali to harm your body?
- We say that the base is limited to edible alkali. Edible alkali, is different from the industrial base of soda ash (sodium carbonate) and baking soda (sodium carbonate), baking soda is soda ash solution or crystal absorption of carbon dioxide after the finished product, the two are essentially no difference. 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: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?
- Alkali has a strong role in degreasing, you can remove the oil on the dry goods on the excess oil;
- Q:What to do with the wall
- Wall latex paint suggest you re-done. Especially to make the primer
- Q:How to see the whole bread of the alkali alkali small
- Look. Cut the dough to see, such as the distribution of uniform distribution of sesame grain size of the hole, indicating that the base is appropriate; such as the emergence of small holes, was slender strip, dough color yellow, that the alkali put more; Uniform macro, dough color dark, that the alkali put less.
- 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 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).
- Q:Would you like some rice when you cooked rice or millet gruel?
- Can, rice porridge plus alkali and do not add alkaline vitamin bl, b2 is almost the same, in order to taste, can be appropriate alkali, harmless to the human body
