This reaction takes place between Silicon (Si) and Sulfuric acid (H2SO4) to form Silicate (Si(SO4)4) and water (H2O). This is a redox reaction, in which Silicon is oxidized from an oxidation state of 0 to +4 and Hydrogen in the sulfuric acid is reduced from an oxidation state of +1 to 0.
- Reaction conditions:
This reaction requires high temperatures to occur. In fact, it is usually conducted at temperatures up to 300-400°C.
- Reaction process:
Silicon is introduced into a container of hot sulfuric acid. When the two substances come into contact, the reaction occurs, producing Silicate and water.
- Phenomena that occur:
When the reaction occurs, you will see a change in the color of the solution from transparent to cloudy white (due to the formation of Silicate). At the same time, there will be steam escaping as the water vapor.
