Advocates of the hydrofluoric acid process argue that both capital and total
operating costs are less than those of sulfuric acid processes for the following
reasons: 1. Smaller and simpler reactor designs are feasible. 2. Cooling water
can be ...

... kg/yr) and HCl (3 3 109 kg/yr). They are most familiar as water solutions,
referred to as hydrofluoric acid and hydrochloric acid, respectively. Recall (
Chapter 13) that hydrofluoric acid is weak, incompletely dissociated in water,
whereas HCl is ...
William Masterton, Cecile Hurley, Edward Neth, 2011
The first step, as always, is to write the major species in the solution. From its
small Ka value, we know that hydrofluoric acid is a weak acid and will be
dissociated only to a slight extent. Thus when we write the major species, the
hydrofluoric ...
