The scientific name of baking soda is sodium bicarbonate.
The scientific name of soda is sodium bicarbonate. It appears as white crystalline powder or opaque monoclinic fine crystals. It is an inorganic salt with strong alkali and weak acid properties. It is weakly alkaline and easily soluble. In water, insoluble in ethanol. Sodium bicarbonate solid begins to gradually decompose above 50°C to form sodium carbonate, water and carbon dioxide gas. When baking soda is mixed with meat, it can destroy the meat fiber and make the meat soft and tender. In daily life, it is usually used to process and cook meat. Using too much can cause the finished product to have an alkaline taste. Baking soda has the effects of relieving acid reflux, regulating uric acid, and deodorizing. In daily life, baking soda is divided into industrial baking soda, edible baking soda and medical baking soda.
Industrial baking soda properties:
White powder or fine crystals, odorless, salty, easily soluble in water, but less soluble than sodium carbonate in water, and the aqueous solution is slightly alkaline sex. Easily decomposes when heated. Decomposes slowly in moist air.
Role of industrial baking soda:
1. SDS sodium-based dry flue gas desulfurizer, widely used in steel plants, coking plants, cement plants, glass plants, power plants, etc.
2. Mine fire extinguishing agent.
3. It is used as the main raw material for industrial alkaline detergents, and also as a washing aid. It is also used as a wool detergent, bath agent, etc.
4. The rubber industry uses it in combination with alum and H pore-forming agent to evenly create pores for the production of rubber and sponge. It is used as a foaming agent for rubber and plastic phenolic resins, and as an assistant foaming agent for polyvinyl chloride and polystyrene.
5. In the printing and dyeing industry, it is used as a fixing agent for dyeing and printing, an acid-base buffering agent, and a post-processing agent for fabric dyeing and finishing. Adding baking soda to dyeing can prevent yarn tubes from developing stains.
6. Used in fire-fighting equipment to produce acid-base fire extinguishing agents and foam fire-extinguishing agents.
7. In the metallurgical industry, it is used as a flux for casting steel ingots.
8. In the machinery industry, it is used as a molding aid for cast steel (sand foundry) sand molds. ?
9. It can also be used in papermaking, film production, tanning, mineral processing, metallurgy, metal heat treatment and agricultural seed soaking agents.
Characteristics of edible baking soda:
White powder or fine crystals, odorless, salty, easily soluble in water, but less soluble than sodium carbonate in water, slightly soluble in ethanol , the aqueous solution is slightly alkaline. Easily decomposes when heated. Decomposes slowly in moist air.
Different from industrial alkali such as soda ash (sodium carbonate) and baking soda (sodium bicarbonate), baking soda is made by absorbing carbon dioxide from a solution or crystal of soda ash. Therefore, baking soda is also called edible alkali (powdered) in some places. Baking soda is solid, round, white in color, and easily soluble in water.
Single salts are divided into: normal salts, acidic salts, and basic salts. Sodium bicarbonate is an acidic salt generated after the neutralization of a strong base and a weak acid. It is weakly alkaline when dissolved in water.
The functions of edible baking soda:
1. Because baking soda in food is alkaline, it can neutralize certain acids and adjust the taste of food. For example, Use it to correct sourness in cakes.
2. Edible baking soda is an important leavening agent in food. When mass-producing steamed buns, fried dough sticks and other foods, soda ash is often melted into water and mixed into the noodles. After heating, it decomposes into sodium carbonate, carbon dioxide and water. The overflow of carbon dioxide and water vapor can make the food more fluffy, and sodium carbonate remains in the food. middle. You can taste it if too much baking soda is added to the steamed buns.
3. Baking soda can be used to remove pesticide residues in food. It is an alkaline substance that can combine with the chlorine in pesticides to effectively reduce pesticide residues. Baking soda can also effectively remove tea stains. After many people drink tea, tea stains form on their cups which are difficult to remove. You can use baking soda to clean them, which can quickly remove the tea stains.
Eating baking soda can be used to brush teeth, but this method is not recommended for long-term use. Generally speaking, baking soda aqueous solution is usually alkaline, so it can suppress the acidity in the mouth, thereby effectively inhibiting the development of bacteria and being beneficial to oral health. Baking soda can also whiten teeth. However, the crystals in baking soda are also relatively large, so it is easy to wear teeth, so long-term use is not recommended, otherwise it will easily damage tooth enamel and cause slight scratches. If necessary, you can choose some toothpaste with baking soda on the market.
The difference between industrial baking soda and edible baking soda:
Baking soda is a very common food additive and chemical raw material in life. Why is it classified? Because baking soda can actually be divided into Several types: edible baking soda, industrial baking soda, and medical baking soda. Different categories have different uses. So how to identify industrial baking soda and edible baking soda? Industrial baking soda and edible baking soda have different uses, impurities, and prices. Identify industrial baking soda and edible baking soda from the three aspects mentioned above.
1. Different purity:
Industrial baking soda contains some organic impurities, lead, arsenic and other metal ions, mechanical impurities, etc.
Edible baking soda has high purity, few impurities, and no toxic or harmful impurities.
2. Different prices:
Industrial baking soda is cheap and cannot be used for food.
The price of edible baking soda is relatively moderate and edible. If you see very cheap baking soda, you generally don’t trust it.
3. Different uses:
Industrial baking soda is suitable for deodorizing, washing dishes, removing tea stains, mopping floors, laundry, and cleaning homes. It is generally used in chemical shops, cleaning supply stores, or Can be purchased at hypermarkets. In the machinery industry, it is used as a molding aid for cast steel (sand foundry) sand molds. In the printing and dyeing industry, it is used as a fixing agent for dyeing and printing, an acid-base buffering agent, and a post-treatment agent for fabric dyeing and finishing.
Edible baking soda is suitable for baking, cooking, personal cleaning, beautification, and cleaning cups and dishes. It can be purchased in DIY skin care products stores and food raw material stores. Since edible baking soda was originally used as a leavening agent for making bread, it is edible, so you don’t have to worry about chemical residues when adding it to water to wipe the floor.
The differences between edible baking soda and medical baking soda are:
1. There are certain differences in levels and standards between edible baking soda and medical baking soda.
2. The purity of medical baking soda and edible baking soda and sodium bicarbonate are different.
3. The cleanliness is also different. Medical baking soda is sterile. Therefore, it must be used under the guidance of a doctor, and at the same time, be sure to pay attention to one step of cleaning and cleaning.
The earliest use of baking soda in China:
As early as the 18th century (the Qianlong period of the Qing Dynasty), the trona lake in the Yike Zhaomeng area had been mined and utilized. By the end of the last century and the beginning of this century , some people have processed trona into "spinium alkali" and sold it to the mainland via Zhangjiakou, which is called "spinium alkali". Sodium bicarbonate (NaHCO?), commonly known as baking soda. Before the invention of the combined alkali production method, the ammonia-alkali method (also known as the Solvay alkali production method) was the most widely used. It was invented by Belgian Ernest Solvay in 1862. After World War I, China's import of soda ash from Europe was blocked.
