Sodium bicarbonate is commonly known as baking soda.

1, soda

Soda is a transliteration of soda. Scientific name of sodium carbonate, common name of soda, also known as soda ash or baking soda powder. There are three kinds of sodium carbonate: sodium carbonate monohydrate, sodium carbonate heptahydrate and sodium carbonate decahydrate. Sodium carbonate decahydrate is also called alkali washing, alkali washing or crystallization alkali.

Among the three kinds of soft drinks, sodium carbonate is the most widely used. It is a very important chemical product and an important raw material for glass, soap, textile, paper making, leather making and other industries. It is also used in metallurgical industry and water purification. It can also be used to make other sodium compounds. As early as the eighteenth century, it was listed as one of the basic chemical raw materials-diacid dibasic with sulfuric acid, hydrochloric acid, nitric acid and caustic soda. In daily life, soda also has many uses. For example, it can be directly used as a detergent. Adding soda when steaming steamed bread can neutralize the acidic substances produced in the fermentation process.

2. Sodium bicarbonate

The scientific name of baking soda is sodium bicarbonate, also known as sodium bicarbonate or acidic sodium carbonate. In addition to baking soda, there are baking soda, fermented soda and heavy alkali. Baking soda is a white crystal, easily soluble in water, and its aqueous solution is weakly alkaline.

Extended data:

1, soda stability

It can be decomposed at high temperature to produce sodium oxide and carbon dioxide. Long-term exposure to the air can absorb moisture and carbon dioxide in the air, generate sodium bicarbonate and form lumps. Strong hygroscopicity, easy to form lumps, and does not decompose at high temperature.

2. Solubility of soda

Soluble in water, slightly soluble in anhydrous ethanol, insoluble in propanol. Sodium carbonate is soluble in water and is a weak acid salt. When it is dissolved in water, it will undergo hydrolysis reaction, making the solution alkaline and corrosive, and it can react with acid to generate corresponding salt and release carbon dioxide.
