What other means of qualitative analysis are used to identify metals

Precipitation, visible-evidenced redox reactions and complexation reactions are used to identify metals.

Explanation:

Hello,

In this case, since you are talking about qualitative analysis, several techniques such as precipitation, visible-evidenced redox reactions and complexation reactions are suitable to identify metals. Such reactions are good enough as long as depending on the metals' cation, it precipitate, redox behavior and complexation will produce a particular color that will allow the identification of the metal.

For instance, to determine the presence of silver, a white precipitate is obtained when chloride ions are placed into a silver-containing sample. The presence of cobalt is substantiated via the formation of a yellowish-brown ionic complex of hexamminecobaltae (II).
