Potassium silicate is a solid, colorless, and odorless state. Its pH level ranges from 10 to 13, creating a strong alkaline environment.

2.2 Chemical properties of K₂SiO₃
K₂SiO₃ is soluble in water and creates an alkaline environment. This compound is insoluble in alcohol. It has the ability to resist corrosion and strong acids.

3. Common chemical equations of K₂SiO₃
   Potassium silicate typically does not react with metals, acids, non-metals, or salts.

4. Synthesis of K₂SiO₃

4.1 Laboratory synthesis of K₂SiO₃
In the laboratory, K₂SiO₃ can be synthesized through the reaction between silicon dioxide (SiO₂) and potassium hydroxide (KOH) under high temperature conditions.

4.2 Industrial synthesis of K₂SiO₃
In industry, K₂SiO₃ is produced through the melting process of silicon dioxide and potassium carbonate at high temperatures, forming a molten solution that is then cooled to create solid potassium silicate.
