Hydrofluoric acid solutions cannot be stored in glass containers because HF reacts readily with silica dioxide in glass to produce hexafluorosilicic acid (H2SiF6).
SiO2(s) + 6 HF(aq) H2SiF6(aq) + 2 H2O(l)
24.0 g SiO2 and 60.0 g of HF react to yield 45.8 g H2SiF6.
(a) What is the limiting reactant?
SiO2
HF
(b) What is the mass of the excess reactant?
(c) What is the theoretical yield of H2SiF6?
(d) What is the percent yield?
