I think the question is "How to Distinguish two different acid chemically "
Add Cu to both the solutions
Ionic-half equation:
1M HCl : Cu(s) + 2H+(aq) --> Cu2+(aq) + H2(g)
Colourless bub ...
AgOH + HCl → H2O + AgCl
AgCl & AgOH are white jelly-like solid
so no observable change
AgOH + HNO3 → H2O + AgNO3
AgOH dissolves
