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.
