Question by 97tedalive: How should I identify an unknown acid in a lab practical?
For my chemistry final, we’re identifying two unknowns, one solid and one liquid. For my liquid, I have tested the pH and have a result of about 1. There are three strong acids HCl, HNO3, and HSO4 on the list of possible unknowns. Does anyone know of any identifying reactions I can use with these acids to find what my unknown is?

Best answer:

Answer by Fred
Add Ba++ to drop out BaSO4 if H2SO4 acid is present.

Add a small piece of Cu metal to each acid. HNO3 is the only one of the three that will dissolve the Cu.

If you have eliminated both the HNO3 and the H2SO4, you can test for the HCl acid with a few drops of AgNO3 solution to get a white precipitate of AgCl, but do this test last as H2SO4 also gives a precipitate of Ag2SO4.
