A nonsulfide scheme of inorganic qualitative analysis is presented, using solutions of hydrochloric acid, sodium acetate, sulfuric acid, and sodium hydroxide as group reagents. The identification of ions is performed by microscopic examination of crystals formed and also by employing color reactions (spot tests). The purpose of this new approach to qualitative analysis is to eliminate the disagreeable odor and corrosive action of hydrogen sulfide and also to achieve more sharp separation of groups. The new scheme with its crystalloscopic and coloriscopic reactions lead to much more certain analytical results.
