Glass reacts with HF to produce
1 \(\mathrm{Na}_{3} \mathrm{AlF}_{6}\)
2 \(\mathrm{H}_{2} \mathrm{SiF}_{4}\)
3 \(\mathrm{H}_{2} \mathrm{SiO}_{3}\)
4 \(\mathrm{SiF}_{4}\)
Explanation:
Glass is \(\mathrm{Na}_{2} \mathrm{O} \cdot \mathrm{CaO} .6 \mathrm{SiO}_{2}\). It reacts with \(\mathrm{HF}\) and gets dissolved. \(\mathrm{Na}_{2} \mathrm{O} \cdot \mathrm{CaO} .6 \mathrm{SiO}_{2}+28 \mathrm{HF} \longrightarrow\) \(2 \mathrm{NaF}+\mathrm{CaF}_{2}+6 \mathrm{SiF}_{4}+14 \mathrm{H}_{2} \mathrm{O} .\)
