Commonly known as baking soda, baking soda powder, baking soda, baking soda, etc. Slow decomposition in humid air or hot air produces carbon dioxide, which is completely decomposed when heated to 270℃. In case of acid, it will decompose strongly to produce carbon dioxide.
Sodium ions are normal to human body and are generally considered non-toxic. However, excessive intake may cause alkalosis, damage the liver and induce hypertension. ?
Solid sodium bicarbonate gradually decomposes above 50℃ to generate sodium carbonate, water and carbon dioxide gas, which is often used as a leavening agent for making biscuits, cakes, steamed bread and bread. Sodium carbonate will remain after the action of sodium bicarbonate, and excessive use will make the finished product have an alkaline taste.
Stable at room temperature and easy to decompose when heated. It decomposes rapidly above 50℃, completely loses carbon dioxide at 270℃, remains unchanged in dry air, and slowly decomposes in humid air. It can react with acids and bases. React with acid to generate corresponding salt, water and carbon dioxide, and react with alkali to generate corresponding carbonate and water.
In addition, it can also react with some salts and double hydrolyze with aluminum chloride and aluminum chlorate to produce aluminum hydroxide, sodium salt and carbon dioxide.
App application
1. When sodium bicarbonate is directly mixed with oil, saponification will occur. Too strong soap flavor will affect the flavor and quality of West Point.
2. Sodium bicarbonate is often used as a neutralizer, for example, to balance the acidity of chocolate. At the same time, it can also deepen the color of chocolate and make it look darker and brighter.
3. If excessive sodium bicarbonate is added to West Point, it will not only destroy the quality and lead to excessive alkaline taste, but also cause symptoms such as palpitation, numbness of lips and temporary loss of taste.
Baking soda can be divided into medicinal, edible and industrial uses, and different kinds of baking soda can be purchased in different places. Among them, industrial baking soda powder has low purity and more impurities, while edible baking soda powder has high purity.
5, baking soda powder is used for household cleaning, which can decontaminate and deodorize. Most of them are acidic substances (H+, such as fatty acids) because they are greasy, stained or smelly. Weak basic hydroxyl OH- will produce neutralization when it meets acidic substances. Apply dirt and wait for a few minutes, then gently wipe it. Don't mix with vinegar.
