  1. Do you have a list of the mineral acids? It would help since there are more than three in practice. The usual ones are HCl, H2SO4, HNO3 but there are many more.
    You can read more about them here.

    Here is a simple solubility chart which should help you identify them. For example, to test for sulfate (if H2SO4), add BaCl2 and a white ppt insoluble in HNO3 denotes H2SO4. AgNO3 gives a white ppt of AgCl with HCl. ETC.
