Question

Explain why
Silicon dioxide is treated with hydrogen fluoride?

Answer 1

when the silicon dioxide is heated with the hydrogen fluoride, it forms silicon tetra fluoride usually the silicon oxide bondis a strong bond and it resists any attack by halogens and most acids. even in the high temperature. however it is attacked by HF.

Answer 2

When silicon dioxide (SiO2) is heated with hydrogen fluoride (HF), it forms silicon tetrafluoride (SiF4).

Usually the Si-O bond is a strong bond and it resists any attack by halogen and most acids, even at a high temperature, However it is attacked by HF.

SiO2 + 4HF ----→ SiF4 + 2H2O

The SiF4 formed in this reaction can further react with HF to form Hydrofluorosilicic acid.

SiF4 + 2HF -----→ H2SiF6

Hope it help you.
