It is important in this practical to: The acid and solid need to be chosen. Use hydrochloric acid to make a chloride, sulfuric acid to make a sulfate, and nitric acid to make a nitrate.

This acid is produced in a high-energy process whereby naturally occurring fluorspar (CaF 2) is reacted with concentrated sulfuric acid under very harsh conditions ... "The most challenging aspect of ...

This acid is produced in a high-energy process whereby naturally occurring fluorspar (CaF 2) is reacted with concentrated sulfuric acid ... high stability and low solubility.

Considering current efforts to prepare oxalic acid at a low cost from CO 2 and biomass, the method may become a viable alternative to the traditional sulfuric acid-dependent HF pathway.
