New chelating ligands, thiocatechol and p-chlorothiocatechol, have been synthesized and the acid dissociation constants were determined by potentiometric method in 50% dioxane-water; $pK_1 ;and; pK_2$ were 7.28, 10.97 for thiocatechol and 6.37, 10.22 for p-chlorothiocatechol, respectively. Color reactions with various metal ions were studied. It was found that the above ligands are specific for Bi(III), Mo(VI) and W(VI) as an analytical reagent.
