Granular alkali and soda ash are two common chemical raw materials that have important applications in industrial production and daily life. Although they both contain "alkali" in their names, they are actually two different chemical substances with different properties and uses

Let's learn about granular alkali. Granular alkali, also known as sodium hydroxide, is an inorganic compound with the chemical formula NaOH. The common solid form is a white granular substance. Granular alkali is a strong alkali that is corrosive and can undergo neutralization reactions with acids. In industry, granular alkali is widely used in areas such as saponification, pulp manufacturing, and food processing. In addition, granular alkali is also used as a cleaning agent and degreaser, which can be used to clean sewers, remove grease stains, and so on

Next, we will introduce soda ash. Soda ash, also known as sodium carbonate, is an alkaline salt compound with the chemical formula Na2CO3. The common solid form is a white crystalline substance. Soda ash is a medium strength alkaline substance that can neutralize acidic substances, but has weaker corrosiveness compared to granular alkali. In industry, soda ash is widely used in glass manufacturing, detergent manufacturing, smelting and other fields. In addition, caustic soda is also used for water treatment and pH regulation

After understanding the basic properties and uses of granular alkali and soda ash, let's summarize the differences between them: 

1 Chemical composition: The main component of granular alkali is sodium hydroxide NaOH, while the main component of pure alkali is sodium carbonate Na2CO3

2. Strength and corrosiveness: Granular alkali is a strong alkali with strong corrosiveness, while pure alkali is a medium strength alkaline substance with weak corrosiveness

3. Application areas: Granular alkali is mainly used in saponification, pulp manufacturing, food processing and other fields, while pure alkali is mainly used in glass manufacturing, detergent manufacturing, smelting and other fields

Overall, both granular alkali and soda ash are important chemical raw materials with important applications in different industrial fields. When using, we need to choose suitable chemical raw materials according to the specific situation to ensure the safety and efficiency of production and life.
