- Q:What is the use of alkali?
- From acid and alkali combined effect
- 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 can release corn is not easy to release niacin, so long-term consumption of corn will not be due to the lack of nicotine in corn and suffering from niacin disease;
- Q:Our home often burn porridge which put a little alkali inside, so delicious, more entrance, eat often harmful to the health of it?
- What to eat is more harmful. So you can add the same time while paying attention to the diversity of the diet.
- 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: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.
- Q:What is white alkali?
- Sodium carbonate [497-19-8] (Na2CO3), molecular weight 105.99. Chemical purity of more than 99.5% (mass fraction), also known as soda ash, but the classification belongs to the salt, does not belong to the base. International trade, also known as soda or alkaline ash. It is an important organic chemical raw materials, mainly for the production of flat glass, glass products and ceramic glaze. But also widely used in life washing, acid and food processing.
- 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 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 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
- Q:How does the edible base use?
- (Sodium carbonate) (chemical formula Na2CO3) and baking soda (sodium bicarbonate) (chemical formula NaHCO3), baking soda is made from soda ash solution or crystal absorption of carbon dioxide after the finished product, both There is no difference between the system. Therefore, edible alkali in some places also known as baking soda (powder). Edible alkali is solid state, round, color white, soluble in water.
