Q:What is alkali sand
Potassium carbonate, white crystalline powder. Density of 2.428g / cm3. The melting point of 891 ° C, the decomposition of boiling point, the relative molecular weight of 138.21. Soluble in water, aqueous solution is alkaline, insoluble in ethanol, acetone and ether. Hygroscopicity, exposure to air can absorb carbon dioxide and moisture, into potassium bicarbonate, should be sealed packaging. Hydrates have a water, dihydrate, sour things. Potassium carbonate aqueous solution is alkaline. Insoluble in ethanol and ether.
Q:What is the role of alkali in the surface
Related to the crowd: the general population can edible production guidance: 1.

Heat, taste bitter; with dehumidification, the food stagnation, detoxification of the role of acid. Note: 1. Do not put the food in the lye soak, so as to avoid raw materials rot, as long as the appropriate concentration of alkaline water will be repeated washing Several times can be; 2. Alkali is inorganic, itself does not have any nutrients, but the role of food cooking can not be underestimated, alkali solution of the electrolyte is the electrolyte, so that food raw materials (such as squid) in the protein molecules in water Ability to enhance the speed of raw materials to speed up, but should pay attention to master the amount of alkali, methods and time to prevent food raw material was too thoroughly, too bad or even deterioration.
Q:Why does not the base noodles rub?
