How to identify 14 unknown chemical solutions?

There are many ways to go about this. Color and smell should help you. (NH4OH is NH3 which has a distinct odor and CuSO4 is VERY blue and smells of sulfuric acid). Also, solubility should be some help. For example, adding HCl to AgNO3 (aq) will result in a white precipitate (AgCl). Metals frequently change color based on crystal field theory. FeCl3 should look different in water and ammonia ( i think). Hope that helps!
