Glass reacts with HF to produce

A

\ceNa3AlF6\ce{Na_3AlF_6}

B

\ceH2SiF6\ce{H_2SiF_6}

C

\ceH2SiO3\ce{H_2SiO_3}

D

\ceSiF4\ce{SiF_4}

Answer

\ceSiF4\ce{SiF_4}

Explanation

Solution

Glass is Na2O.CaO.6 SiO2 {Na_2O . CaO . 6 \, SiO_2}. It reacts with HF and gets dissolved. Na2O.CaO.6 SiO2+28 HF−>2 NaF+CaF2+6 SiF4+14 H2O {Na_2O . CaO . 6 \, SiO_2 + 28 \, HF -> 2\, NaF + CaF_2 + 6 \, SiF_4 + 14 \, H_2O}
