Question

The product obtained when silica reacts with hydrogen fluoride is

Answer 1

Silicon dioxide react with hydrogen fluoride to produce silicon tetrafluoride and water. Hydrogen fluoride - diluted solution.

SiO2 + 4 HF = SiF4 + 2 H2O

Answer 2

Explanation:

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

The chemical reaction equation for the reaction is as follows.

         $SiO_{2} (s) + 4HF (aq) \rightarrow SiF_{4}(g) + 2H_{2}O(l)$

This reaction is a double displacement reaction because there is exchange of ions of two compounds.
