Hydrofluoric acid, HF (aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). Sodium silicate Na2SiO3, for example, reacts as follows:
Na2SiO3(s) + 8 HF (aq) → H2SiF6(aq) + 2 NaF(aq) + 3 H2O(ɭ)
(a) How many moles of HF are needed to react with 0.300 mol of Na2SiO3?
(b) How many grams of NaF form when 0.500 mol of HF reacts with excess Na2SiO3?
(c) How many grams of Na2SiO3 can react with 0.800 g of HF?
