Glass reacts with HF to produce
- A \(\mathrm{SiF}_4\)
- B \(\mathrm{Na}_2 \mathrm{SiO}_3\)
- C \(\mathrm{H}_2 \mathrm{SiO}_3\)
- D Silicones
Answer & Solution
Correct Answer
(A) \(\mathrm{SiF}_4\)
Step-by-step Solution
Detailed explanation
Silica \(\left(\mathrm{SiO}_2\right)\) of glass reacts with \(\mathrm{HF}\) to produce silicon tetrafluoride \(\left(\mathrm{SiF}_4\right)\). \(\mathrm{SiO}_2+4 \mathrm{HF} \longrightarrow \mathrm{SiF}_4+2 \mathrm{H}_2 \mathrm{O}\)
