Silicon does not react chemically with water at room temperature, but it is soluble in alkaline solutions, and hydrogen gas is released to form the corresponding alkali metal silicate solution, which can react with water vapor at scalding temperatures. . effect.
Silicon is insoluble in water, nitric acid and hydrochloric acid, but soluble in hydrofluoric acid and alkalis.
We can conclude that silicon and water do not react at room temperature.
Detailed information:
1. Silicon has obvious non-metallic properties and can be dissolved in alkali metal hydroxide solutions to produce (meta)silicate and hydrogen
2. It can react with elemental halogens, nitrogen, carbon and other non-metals under heating
3. It can also react with certain metals such as Mg, Ca, Fe, Pt, etc. to form silicides;
4. Insoluble in general inorganic acids;
5.

1: Hydrogen peroxide is a strong oxidant and can react with iron.
Two: Hydrogen peroxide itself will decompose at room temperature to produce oxygen. The reaction rate is even higher in the presence of a catalyst. Perhaps the impurities on the surface of the iron-silicon alloy can also be used as a catalyst to accelerate the decomposition of H2O2.
