Classical qualitative inorganic analysis is a method of analytical chemistry which seeks to find the elemental composition of inorganic compounds. It is mainly focused on detecting ions in an aqueous solution, therefore materials in other forms may need to be brought to this state before using standard methods. The solution is then treated with various reagents to test for reactions characteristic of certain ions, which may cause color change, precipitation and other visible changes. Qualitative inorganic analysis was universally taught in most universities until the 1980's either in Inorganic chemistry or in Analytical chemistry classes. Since then, it has disappeared even the curricula of Chemistry majors, due to its limited use by Chemistry professionals.
