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?
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

Q:Does the alkaline battery pollute the environment?
It is understood that, in order to maintain the sustainable development of the battery industry, China Battery Industry Association to "environment-friendly and harmonious development" as the theme, in August this year, organized a nationwide "green alkaline manganese battery products" evaluation activities. After testing, Guangzhou Hutou Battery Group Co., Ltd. production of "555" brand alkaline manganese batteries and other 11 key enterprises of alkaline manganese batteries mercury content are lower than the mercury-free mercury content limit indicators, in full compliance with the provisions of the national nine ministries.
Q:Is the plant base a food base?
A basic nitrogen - containing organic compound in a living organism. Most of them exist in plants and are present in animals. With a ring structure, insoluble in water, and acid can form a salt, a certain optical and absorption spectrum, most of the bitter taste, was colorless crystal, a small number of liquid.
Q:What is white alkali?
White alkali is sodium carbonate, is a hydrolysis of alkaline water content of crystalline water carbonate, caustic soda, caustic soda, caustic soda, in the chemical raw materials store can buy
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:Alkali soda water
Soda water is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical disinfectant, drinking and neutralizing the body's acid-base balance, changing the acidic constitution. Most of the soda water sold on the market is a synthetic carbonated beverage that is compressed into purified water and added sweeteners and fragrances. Soda water is a carbonated beverage, is pressed into purified drinking water into carbon dioxide, and add sweeteners and spices. He is an aqueous solution of sodium bicarbonate, containing weakly alkaline, medical topical sterilization, oral administration can be integrated within the body's acid-base balance, change the acidic body. Sodium bicarbonate is what we say baking soda molecular formula NaHCO3 is usually said that the surface screwdriver, but this is not directly joined the surface screwdriver, the market selling soda water is mostly in the purified drinking water into the carbon dioxide, and add Sweeteners and fragrances of synthetic synthetic carbonated beverages. Baking soda: NA2CO3 soda: NAHCO3, weak base. Medical topical disinfection can be sterilization, oral administration can cure too much acid. Soda water is actually carbonated water Well, Coke, whiskey what is inside. Pure soda water also has, usually the equipment, supermarkets have to sell. Can be used for cocktails. Can go to the pharmacy to buy small soda tablets with warm water to the system, but the concentration is not good to master.
