Sio2 and sf6 reaction equationWhen SiO2 was etched, if the process was performed by using the SiF6, the reaction process could be expressed as: SiF6 + e--SiF5 + F (free radical) +2e, SiO2 + 4F--SiF4 (gas) + O <anno data-annotation-id ="0044000 - 4440 - 4000 - 4000 - 8000 - 80000000000"></anno>.

Reaction equation of NaF and SiO22NaF + H₂SiO₃ = Na₂SiO₃ + 2HF↑。However, it was important to note that sulfuric acid was a weak acid. When this reaction occurred in a solution, if the sulfuric acid was in a precipitative state, the reaction might be difficult to carry out.

Does SiO2 react with the base solution?Under normal conditions, SiO2 can react with a strong base solution. For example, the chemical equation for reacting with a solution of soda ash is SiO2 + 2NaOx = Na <2> SiO2 + H <2> O. The reaction of the acidic dioxide SiO2 with a base can produce a sulfuric acid ion. However, the reaction between SiO2 and the solid state of NaOx (or the solid state of KhOx) would only occur under strong heat.
