Carol asks…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?Nancy answers:Add Ba++ to drop out BaSO4 if H2SO4 acid is present.
Add a small piece of Cu
