Calcium hydroxide / Slaked Lime
Calcium hydroxide, traditionally called slaked lime, is an inorganic compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder. It has many names including hydrated lime, builders' lime, slack lime, cal, or pickling lime. Calcium hydroxide is used in many applications, including food preparation.

- 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: 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: How does the edible base use?
- 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: 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: What is the name of the alkali?
- Its scientific name is [sodium carbonate].
- 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?
- Alcohol and dark green vegetables due to the excessive spraying of pesticides and the adhesion of organic acids or sulfide, which can keep the original color of vegetables, and remove pesticides on vegetable pollution;
- Q: The commonality of the base
- Alkaline solution can react with acid and alkali indicator
- 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: 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: What is the alkaline powder? Baking soda? Sodium carbonate or something else?
- Baking soda is very easy to absorb the air of the air, so when not in use when the best way to retract, such as sealed cans or folder chain or milk powder cans. Use, you can use a commercially available pepper to retract, but not Add the lid, pepper cans of the hole is very easy to sprinkle the small soda.There is no pepper cans, you can also have a hole in the cloth, such as not the yarn quality curtains, mosquito nets, etc., tied tied to the general bottle, It is easy to pour out to use.If you just want a simple moisture and deodorant, you can put the small soda in the old cotton socks, and then sealed with a rope, and then any use can be
