Abstract: Resorcylidenethiosemicarbazone forms colored complexes with metals that can be used for their identification. By test tube reaction, Fe⁺⁺⁺ is green-brown, Co⁺+ brown-red, Ni⁺⁺ red-brown, Cu⁺⁺ gray-brown ppt., Hg⁺⁺ orange-red ppt., Ag⁺ yellow ppt. changing to brown, Mn⁺⁺ (in concd. soln.) yellow-brown ppt., (in dild. soln.) red-brown, and Mo⁶⁺ yellow. By the spot reaction on filter paper, Fe⁺⁺⁺ is intensely green-brown, Co⁺⁺ red-brown, Ni⁺⁺ red-brown, Cu⁺⁺ green, Hg⁺⁺ yellow, Ag+ yellow changing to brown, Mn⁺⁺ dark-brown, and Mo⁶⁺ yellow.
