People often say that soda is sodium bicarbonate (NaHCO3), also known as baking soda or baking soda powder.

Chemical composition and properties of 1. soda

The chemical name of soda is sodium bicarbonate, and the chemical formula is NaHCO3. It is a white crystalline powder, which is easily soluble in water and alkaline in water. Soda has a buffering effect, which can neutralize acid substances and can also be neutralized by acid substances. Therefore, soda is often used as neutralizer, cleaner and food additive in many domestic and industrial applications.

2. Preparation method of soda

Soda can be prepared by a reaction process. A common preparation method is to react soda ash (sodium hydroxide) with carbon dioxide gas to generate sodium bicarbonate. This method is usually used in industrial production. In addition, soda can also be extracted from natural ore by heating and decomposing ore stones containing sodium bicarbonate.

3. Application field of soda

Soda is widely used in many fields. The following are some main application fields: cleaning agents and disinfectants: soda is often used as a cleaning agent to remove oil stains, dirt and odor. It also has bactericidal effect, so it is often used in cleaning kitchens, bathrooms and other family environments.

Baked food: Soda is a common baking powder and is used as a starter. In the process of making baked goods such as bread, cakes and biscuits, soda can react with acidic components to produce carbon dioxide gas, which makes dough expand and ferment.

Neutralizer: Soda is a weakly alkaline substance, which can neutralize acidic substances. Therefore, in some cases, soda is used as a neutralizer to neutralize acidic soil, acidic wastewater or acidic substances splashing into the skin.

Medicine and medical use: Soda is also used in medicine manufacturing and medical field. For example, in some antacids and stomach medicines, soda is used as a buffer to reduce the irritation of gastric acid to gastric mucosa.

To sum up, soda is a common chemical substance, and its chemical name is sodium bicarbonate. It has a variety of applications, including cleaning agents, baked goods, neutralizers and pharmaceutical manufacturing. The chemical properties of soda make it a multifunctional substance, which plays an important role in daily life and industrial production.
