China Factory Supply Wholesales Food Grade Sodium Carbonate Soda Ash Dense

Sodium carbonate (chemical formula Na₂CO₃), commonly known as soda or pure ash, is an important inorganic compound. It is white granular or crystalline, soluble in water, and has a strong alkalinity. Sodium carbonate is widely used in the chemical industry, detergents, and glass production.

In addition, sodium carbonate is also used in the food industry as an acidity regulator or fermentation agent. It can also remove calcium and magnesium ions from water in water treatment, playing a role in softening water quality. Due to its alkalinity, sodium carbonate is often used to neutralize acidic substances.

Products FeatureFeature

Sodium carbonate (Na₂CO₃) is a common inorganic salt with a series of remarkable chemical and physical characteristics. It is white crystalline or granular, easily soluble in water, and the solution is alkaline. Its solubility increases with increasing temperature, and the pH value of the aqueous solution is usually around 11, which is strongly alkaline. An important chemical property of sodium carbonate is that it can react with acids to produce corresponding salts and carbon dioxide gas. For example, sodium carbonate reacts with hydrochloric acid to produce sodium chloride and carbon dioxide.

In addition, sodium carbonate is also highly hygroscopic and can absorb moisture from the air to form sodium bicarbonate or other hydrates. At high temperatures, sodium carbonate decomposes to produce carbon dioxide gas and sodium oxide (Na₂O). This property makes it used in metal refining and other high-temperature industrial processes at high temperatures.

Sodium carbonate is widely used, mainly in glass manufacturing, chemical synthesis, detergent production, water softening, food processing and other fields. In the glass industry, sodium carbonate is an important raw material, which can lower the melting point of raw materials and promote the melting of glass.

Production DetailsDetails

Sodium carbonate (Na₂CO₃) is widely used in various industries, mainly in the following four aspects:

1. **Glass manufacturing**

Sodium carbonate is one of the important raw materials in the glass industry. In glass production, its main function is to reduce the melting point of raw materials and make glass raw materials easier to melt. Usually, about 200-250 kg of sodium carbonate is required to produce 1 ton of ordinary float glass.

2. **Chemical industry**

In the chemical industry, sodium carbonate is used as a reactant, catalyst and neutralizer. It is used to produce chemicals such as sodium chloride, sodium hydroxide, and sodium bicarbonate. In addition, sodium carbonate is also used in washing and bleaching processes to play a role in decontamination and softening water. The amount used depends on the hardness of the treated water and the desired effect.

3. **Water treatment**

Sodium carbonate is widely used in the field of water treatment, especially softening water quality. It removes the hardness of water by precipitating calcium and magnesium ions in water. Usually, 50-100 kg of sodium carbonate is added to 1000 cubic meters of water to achieve an effective softening effect.

4. **Food Industry**

In food processing, sodium carbonate is used as an acidity regulator, leavening agent or leavening agent. It is used in baking powder to help food rise, and is common in baked goods. The dosage is usually 2-4 grams per kilogram of flour, depending on the product requirements.

These application areas show the importance of sodium carbonate as a multifunctional chemical, and its dosage varies depending on the specific use.
