Question

Solid calcium fluoride (CaF2) reacts with sulfuric acid (H2SO4) to form solid calcium sulfate (CaSO4) and gaseous hydrogen fluoride (HF).  The HF is then dissolved in water to form hydrofluoric acid.  A source of calcium fluoride is fluorite ore containing 96.0 wt% CaF2 and 4.0 wt% SiO2

In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wt% aqueous sulfuric acid, supplied 15% in excess of the stoichiometric amount.  95% of the ore dissolves in the acid.  The HF(g) exiting the reactor is subsequently dissolved in enough water to produce 60.0 wt% HF (aq).  ASSUME THE OTHER 5% OF THE ORE ACTS AS INERTS, AND REMAINS IN THE REACTOR (I.E., DOES NOT APPEAR IN THE OUTLET STREAM).

Calculate the product composition from the reactor, and also the amount of water required to generate a 60.0 wt% HF solution.
