Q: I have been very confused, baking soda and edible alkali surface is the same thing? Tea in the consumption of baking soda is not become alkaline? Can drink? How to quickly become alkaline? In addition to more melon Fruit and vegetables outside: Alkaline foods such as kelp, white radish, tofu, red beans, soybeans, apples, onions, kale, tomatoes, spinach and bananas are all things that are not easy to cause appetite but are beneficial to the body. Acidic foods, such as grapes, strawberries, lemons, etc., which are drooling, and in fact these things are typical of alkaline foods.

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 alkali active aggregate?: What is the base active aggregate? "Ordinary concrete with gravel or pebble quality standards and test methods JCJ53-92" provides: alkali active aggregate - with cement or concrete in the alkali chemical reaction Aggregate.

Q: What is called alkali recovery: For alkali recovery, the assessment of the extraction section is the concentration and temperature. Concentration: 8 ° Be; Temperature: 70-80 ° C.

Q: Last called me to buy salt, but can buy a bag of alkaline powder to go home. Want to know what can use alkali powder?: Alkaline powder can treat burns. If the scald area pony immediately coated with alkaline powder, and then drop a few drops of water, alkali powder will be dissolved immediately after the water.

If the area of burns larger, can be soaked with alkali powder soak for about half an hour or an hour.

Q: Alkaline pool can breed what: In the future of adult fish sales process found that after long-distance transport, part of the fish surface congestion, affecting the survival rate of transport and marketing. This may be associated with the addition of fish oil in the larger amount, resulting in high fish fat, muscle softness. Suggested in the late breeding, should reduce or even stop the addition of fish oil, and should increase the water flow, stimulate the fish, to achieve the purpose of exercise to improve the survival rate of transport.

Q: What is the important character of Chinese made alkali?: (1) NH3 + H2O + CO2 = NH4HCO3 (2) NH4HCO3 + NaCl = NH4Cl + NaHCO3 ↓ (3) 2NaHCO3 (heating) = Na2CO3 + H2O + CO2 ↑ That is: ① NaCl (saturated) + NH3 + H2O + CO2 = NH4Cl + NaHCO3 ↓ ②2NaHCO3 = Heating = Na2CO3 + H2O + CO2 ↑ Ammonia reacts with water and carbon dioxide to form a molecule of ammonium bicarbonate, which is the first step. The second step is: ammonium bicarbonate reacts with sodium chloride to form a molecule of ammonium chloride and sodium bicarbonate precipitation, sodium carbonate is precipitated because it is less soluble.

Q: How to go to the base of the teapot: Many people like to drink tea, but the cup of tea is difficult to remove the tea, tea wall grows a layer of tea, containing cadmium, lead, iron, arsenic, mercury and other metal substances. They are in the tea into the body, and food in the protein, fat and vitamins and other nutritional compounds, resulting in insoluble precipitation, hinder the absorption of nutrients. At the same time, these oxides into the body can cause nerve, digestion, urinary hematopoietic system diseases and dysfunction, especially arsenic, cadmium can cause cancer, causing fetal malformations, health hazards. Therefore, tea drinking habits, should always be timely cleaning tea inside the tea. In order to make you no longer a big headache for the matter, the following describes several ways in addition to tea: (1) remove the metal tea on the tea off, the use of metal tea, Become black, such as with medium-sized cleaning agent can not wash, can be soaked with vinegar, or soaked with bleach can easily peel. (2) to remove the cup or teapot on the tea, cups, teapots with a long time, it will be a lot of tea, with a sponge dipped in salt friction, can be easily removed. (3) in addition to small pieces of tea, can be soaked in bleach or clean powder solution, and place a night, you can remove the tea scale. (4) can be used toothpaste or broken eggshell scrub, and then rinse with water can be.

Q: A bit tall please help me one!: As a result of the community on the misuse of waste batteries, such as: a button battery can pollute 600,000 cubic meters of water, a 5-cell can make a square meter of land is not grass, resulting in some public opinion bias, so that our waste disposable battery recycling And chaos dealing with the work, resulting in some unnecessary waste and mistakes.
