Try google and also why do you double post....think you'll get more help that way?.....wrong, so delete one of your posts as it doesn't help and do
some foot work yourself then post what you know and still can't understand then you will get some help..........solo

this is not possible, sulfuric acid is the only acid that can not be displaced from its salts,
becouse in other situations (e.g. Sodium Chloride and Sulfuric acid yields hydrochloric acid). the acid produced has to be less strong than the acid
used to displace it from the salt with. sulfuric acid is stronger than hydrochloric, so this works. becouse there is no acid stronger than sulfuric it
won't work.

There was a thread on this over at roguesci.org. As I remember, they got some sulfuric acid by electrolysis of CuSO<sub>4</sub>, but not
much.

This isn't the whole reality. As far as I know HCl(pKs-6) is a stronger acid than H2SO4 (pKs-3). The thing is that you need an acid with an higher
boiling point than the acid you'll liberate. HCl is very volatile so it will leave the reaction system because the concentrated sulfuric acid you use
will capture all water. It's also possible to liberate HCl with AHSO4 (A=>alkali metall) which is a weak acid.
On the other hand it won't be possible to liberate phosphoric acid(weaker acid then HCl) from phosphate with HCl because your gaseous HCl will leave
your condensor far before the H3PO4 will do.
