Question

the product obtained when silica reacts with hydrogen fluoride is.....?

Answer 1

silicon fluorine and hydrogen
Si + Hf =sif+ H

Answer 2

Explanation:

When silica reacts with hydrogen fluoride then it results in the formation of silicon tetrafluoride and hydrogen gas.

The chemical reaction equation for the same is as follows.

     $Si + 4HF \rightarrow SiF_{4} + 2H_{2}$

Silicon tetrafluoride is a colorless compound and it is volatile in nature.

It is found in huge amounts near volcanic plumes.
