Glass reacts with HF to produce

  1. A \(\mathrm{SiF}_4\)
  2. B \(\mathrm{Na}_2 \mathrm{SiO}_3\)
  3. C \(\mathrm{H}_2 \mathrm{SiO}_3\)
  4. D Silicones
Verified Solution

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 \(\left(\mathrm{SiF}_4\right)\). \(\mathrm{SiO}_2+4 \mathrm{HF} \longrightarrow \mathrm{SiF}_4+2 \mathrm{H}_2 \mathrm{O}\)
