JEE Advanced · Chemistry · p Block Elements (Group 13 & 14)

SiO_ 2 is attacked by which one / ones of the following?

SiO2\mathrm{SiO}_{2} is attacked by which one / ones of the following?

Options

  1. AHF
  2. Bconc. HCl
  3. Chot NaOH\mathrm{NaOH}
  4. DFluorine

Correct answer

D. Fluorine

Step-by-step solution

Hint:
SiO2( s)+F2( g)→SiF4(aq.)+O2( g)\mathrm{SiO}_{2}(\mathrm{~s})+\mathrm{F}_{2}(\mathrm{~g}) \rightarrow \mathrm{SiF}_{4}(\mathrm{aq} .)+\mathrm{O}_{2}(\mathrm{~g})
SiO2( s)+6HF\mathrm{SiO}_{2}(\mathrm{~s})+6 \mathrm{HF} (aq.) →H2SiF6\rightarrow \mathrm{H}_{2} \mathrm{SiF}_{6} (aq.) +2H2O(ℓ)+2 \mathrm{H}_{2} \mathrm{O}(\ell)
SiO2( s)+2NaOH(\mathrm{SiO}_{2}(\mathrm{~s})+2 \mathrm{NaOH}( aq. )→Na2SiO3( s)+H2O(ℓ)) \rightarrow \mathrm{Na}_{2} \mathrm{SiO}_{3}(\mathrm{~s})+\mathrm{H}_{2} \mathrm{O}(\ell)
