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 acid will be represented in its dominant form, as HF. The major ...

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 ...
