The equation KOH + SiO2 -> K2SiO3 + H2O

1. Detailed information about the equation KOH + SiO₂ -> K₂SiO₃ + H₂O:

The equation is not balanced, after balancing it will be: 2KOH + SiO₂ -> K₂SiO₃ + H₂O.

Includes:

• KOH: is an alkali salt called potassium hydroxide, a strong alkaline, white solid that is easily soluble in water.

• SiO₂: is an oxide of silicon, known as silicon dioxide, a colorless, odorless solid that is slightly soluble in water.

• K₂SiO₃: is potassium silicate salt, a colorless solid.

• H₂O: is water.

2. Reaction conditions:

• Temperature: This reaction usually occurs at high temperatures.

• Pressure: This reaction occurs at normal pressure.

3. Reaction process:

• The reaction process takes place when potassium hydroxide (KOH) reacts with silicon dioxide (SiO₂) to create potassium silicate (K₂SiO₃) and water (H₂O).

4. Phenomena occurring:

• When KOH is introduced into the solution containing SiO₂, a white precipitate phenomenon of K₂SiO₃ will appear.

• If the reaction occurs at high temperatures, steam will be produced.
