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 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:Why does not the base noodles rub?
Yes, you are not practicing
Q:What is the alkaline powder? Baking soda? Sodium carbonate or something else?
Alkaline powder is used to do the soda with bread, and the same function with the soda powder. Soda powder rostmarry; alias also known as: sodium bicarbonate In the production practice, high-yielding dairy cows are in high energy, high protein levels. Sodium is also called "soda powder", not called "Sopram". (Other names) baking soda; sodium bicarbonate; acid sodium carbonate;
Q:What is the role of alkali in the surface
Related to the crowd: the general population can edible production guidance: 1. Alcohol can remove the salad in the oil, the method is to wait until with the aroma of salad oil heated to hot, put a certain amount of soda ash, slowly with chopsticks Even can be; 2. Alcohol can remove the dough's sour taste, and can make the bread bulky white, but can not add too much, otherwise the bread will become yellow or crack, the taste will become bitter. 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:What is the difference between baking base and common base?
The main content is not the same
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 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:Do you eat too much alkali to harm your body?
We say that the base is limited to edible alkali. Edible alkali, is different from the industrial base of soda ash (sodium carbonate) and baking soda (sodium carbonate), baking soda is soda ash solution or crystal absorption of carbon dioxide after the finished product, the two are essentially no difference. Edible alkali is solid state, round, color white, soluble in water. 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: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.
