Sodium bicarbonate. Sodium bicarbonate, chemical formula Nahco, commonly known as baking soda. White fine crystals, less soluble in water than sodium carbonate.
It is also an industrial chemical, with solids above 50 beginning to gradually decompose to produce sodium carbonate, carbon dioxide and water, and completely decompose at 270.
Sodium bicarbonate is an acid salt formed after neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water. This property allows it to be used as a leavening agent in the food production process. Sodium bicarbonate will remain sodium carbonate after action, and too much use will make the finished product have an alkaline taste.

The scientific name of baking soda is sodium bicarbonate, which is a weakly alkaline white powder, commonly known as "baking soda", "baking soda", "heavy cao", the solubility in water is less than sodium carbonate, is an industrial chemical, may be toxic.
The chemical properties of sodium bicarbonate are not stable, it is easy to decompose when heated, and it will slowly decompose in humid air, and it will begin to react to form carbon dioxide at about 50, and it will all become sodium carbonate at 100. Sodium bicarbonate can be rapidly decomposed in weak acid, and its aqueous solution begins to decompose carbon dioxide and sodium carbonate at 20, and all decompose at the boiling point, but it is not soluble in ethanol.

<>1. Baking soda (scientific name is sodium bicarbonate) is a weakly alkaline white powder, commonly known as "baking soda", "baking soda" and "heavy grass". Its solubility in water is less than that of sodium carbonate. It is an industrial chemical. Poisonous.
2. The chemical properties of sodium bicarbonate are unstable. It decomposes easily when heated, and slowly decomposes in moist air. It will start the reaction at about 50°C to form carbon dioxide and at 100°C it will all become sodium carbonate.
Sodium bicarbonate decomposes rapidly in weak acids. Its aqueous solution begins to decompose carbon dioxide and sodium carbonate at 20°C, and all decomposes when it reaches its boiling point, but it is insoluble in ethanol.
3. Sodium bicarbonate has many uses. For example, it can be used directly as a raw material in the pharmaceutical industry and can also be used for hyperacidity. It is a widely used leavening agent in the food industry and can be used to produce biscuits, cakes, steamed buns, bread, etc.
It is also a producer of carbon dioxide in soda drinks.

1. In addition to the name "baking soda", baking soda powder also has the names of baking soda, soda powder, sodium bicarbonate and so on. In appearance, baking soda is white crystals. For example, adding too much sodium bicarbonate to West Pastry will not only destroy the quality and cause excessive alkaline taste, but also cause palpitations, numbness of the lips, and temporary loss of taste.
2. Baking soda is divided into three types: medicinal, edible, and industrial, and the place of purchase is different depending on the type. Among them, medicinal baking soda can be bought in pharmacies, large supermarkets, and north and south grocery stores; If you want to use it in cooking, be sure to choose baking soda. The purity of baking soda powder for industrial use is low, and there are more impurities, and the purity of baking soda powder for edible consumption is higher.
3. Baking soda begins to gradually decompose to produce sodium carbonate, carbon dioxide and water above 50, and completely decomposes at 270. Sodium bicarbonate is an acid salt formed after the neutralization of strong alkali and weak acid, which is weakly alkaline when dissolved in water.

The difference between baking powder and baking soda is: different properties, different pH, and different uses.
First, the nature is different.
1. Baking powder: Baking powder is a white powder made of baking soda powder with acidic materials and corn flour as a filler.
2. Baking soda: Baking soda, which is sodium bicarbonate, is an inorganic salt with a white crystalline powder.
Second, the pH is different.
1. Baking powder: Baking powder is added to balance its pH after precise testing, so it is neutral powder.
2. Baking soda: Baking soda is an alkaline substance, and using too much will make the finished product have an alkaline taste.
Third, the use is different.
1. Baking powder: Baking powder is mainly used for the rapid fermentation of grain products. It is used in large quantities when making cakes, cakes, buns, steamed buns, shortbreads, bread and other foods.
2. Baking soda: Baking soda is used as a leavening agent for making biscuits, pastries, steamed buns, and bread.

The scientific name for baking soda is sodium bicarbonate, which is a chemical substance. Its chemical formula is NaHCO3, which is soluble in water and produces alkaline. As a common food additive, baking soda is widely used in the baking process.
It uses carbon dioxide in sodium bicarbonate to cause the dough to rise and make the pastry softer. Baking soda can also be used for cleaning, making cleaning easier due to its alkaline ability to neutralize acidity. Use baking soda in moderation, excessive use may cause physical discomfort.
It is worth mentioning that baking soda is also found in cosmetics. It has excellent performance in exfoliation, deeply cleansing pores, removing impurities such as old keratin and oil, and achieving a deep cleansing effect. However, prolonged use of products containing baking soda may damage the self-protective barrier, resulting in excessive dryness or sensitivity.
Therefore, it is recommended to decide the frequency and amount of use according to your own situation when using this type of product slippage, so as not to cause problems.
Baking soda has a wide range of applications in life as a chemical. When it comes to baking and cleaning, it brings convenience and cleanliness. In cosmetics, it also plays an important role.
Use baking soda in moderation to avoid negative effects. For people who are sensitive or prone to allergies, it is recommended to take a test before use and consult a professional for advice. Doctors from tertiary hospitals recommend using pure air cleansing liquid for the best effect.

Baking soda, the chemical name is sodium bicarbonate, and the English name is sodium bicarbonate. Its sub-luminal comma formula is NaHCO3, which is a white solid powder with alkaline properties.
Baking soda has many uses in life. It can be used in baked goods, as a leavening agent for flour. It can also be used as a cleaner to remove dirt and odors.
It can also be used for drug preparation, relieving acid reflux, bad breath, and other problems. Baking soda is a very practical substance.
Baking soda is an alkaline substance that reacts with acids to produce carbon dioxide gas. That's why baking soda is used in the baking process: when baking soda is mixed with an acidic substance such as vinegar or lemon juice, it creates a lot of bubbles that make the dough swell and ferment.
The alkaline properties of baking soda can also be used to remove stains and odors that are difficult to clean.
In addition to the common uses mentioned above, there are some lesser-known uses for baking soda. For example, it can add some baking soda to the bathtub to help exfoliate and make it smoother. Baking soda can also be added to shampoos to effectively cleanse the scalp and hair.
Baking soda is a very practical substance that has a wide range of applications in life. Whether it's baking, cleaning, drug preparation or beauty, it has a unique role. Therefore, we should understand and be good at making use of this versatile little thing.
