Chapter 4, Problem 4.71P
Solid calcium fluoride (CaF2) reacts with sulfuric acid to form solid calcium sulfate 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 .OS? SiO2.
In a typical hydrofluoric acid manufacturing process, fluorite ore is reacted with 93 wtS? aqueous sulfuric acid, supplied 15% in excess of the stoichiometric amount. Ninety-five percent of the ore dissolves in the acid. Some of the HF formed reacts with the dissolved silica in the reaction
6HF + SiO2(aq) -» H2SiF6(s) + 2H2O(1)
The hydrogen fluoride exiting from the reactor is subsequently dissolved in enough water to produce 60.0 wtS? hydrofluoric acid. Calculate the quantity of fluorite ore needed to produce a metric ton of aqueous hydrofluoric acid. Note: Some of the given data are not needed to solve the problem.

Four thousand kilograms per hour of a solution that is one-third K,CrO, by mass is joined by a recycle stream containing 36.4% K2CrO7, and the combined stream is fed into an evaporator. The concentrated stream leaving the evaporator contains 49.4% K,CrO; this stream is fed into a crystallizer in which it is cooled (causing crystals of K,CrO, to come out of solution) and then filtered. The filter cake consists of K,CrO, crystals and a solution that contains 36.4% K,CrO, by mass; the crystals account for 95% of the total mass of the filter cake.

Aluminum sulfate can be made by the following reaction: 2AlCl3(aq)+3 H2SO4(aq)➡Al(SO4)3(aq)+6HCl(aq). It is quit soluble in water, so to isolate it the solution has to be evaporated to dryness. This drives off the volatile HCl, but the residual solid has to be heated to a little over 200 celsius to drive off the water. In one experiment, 25.0 g of AlCl3 were mixed with 30.0 g of H2SO4.
