Add a drop a the acid to a solution of silver nitrate. If you get a precipitate it's HCl:
AgNO3(aq) + HCl(aq) --> AgCl(s) + HNO3(aq)

you can test for chloride ions by adding dilute nitric acid to the solution, then adding silver nitrate solution. If the solution contains chloride ions, a white precipitate of silver chloride will form, this will turn purple-grey in sunlight.
You can test for sulphate ions by adding nitric acid to the solution, then add barium nitrate solution. If the sulphate ions a re present, a thick precipitate of barium sulphate will form. These two test can be used to differentiate between the two acids, because hydrochloric acid contains chloride ions, whilst sulphuric contains sulphate ions.

Put a small sliver of silver in the acids . The sulfuric will turn the silver dark into silver sulfide.
