The equation NaOH + SiO2 -> Na2SiO3 + H2O

1. Detailed Information about the Equation NaOH + SiO₂ -> Na₂SiO₃ + H₂O

The above chemical equation represents the chemical reaction between sodium hydroxide (NaOH) and silicon dioxide (SiO₂) to form sodium metasilicate (Na₂SiO₃) and water (H₂O).

The balanced and complete equation would be 2NaOH + SiO₂ -> Na₂SiO₃ + H₂O.

2. Reaction Conditions

This reaction typically occurs at high temperature and in alkaline environment (as NaOH is a strong alkali).

3. Reaction Process

When NaOH and SiO₂ are combined and heated, molecules of NaOH and SiO₂ start to react with each other. During the reaction process, NaOH will provide Na+ to combine with [SiO3]2- from SiO₂ to form Na₂SiO₃, whilst creating H₂O.

4. Phenomena Occurring

During the reaction process, you will observe a rise in temperature and the formation of the new compound Na₂SiO₃ in the form of white solid.
