Abstract: The properties of inner complex salts of phthalocyanine with metals are discussed. Cu phthalocyanine in concd. H₂SO₄ can be used as new test for oxidative agents, NO₂^-, NO₃^-, ClO₃^-, BrO₃^-, IO₃^-, Cr₂O₇^2-, and MnO₄^-. The anions in higher concn. disturbing the reaction are S₂^-, S₂O₃^2-, SO₃^2-, SCN^-, Br^-, and I^-. The selectivity of the reaction is increased by pptg. the disturbing anions with a soln. of Hg(OAc)₂ and BaCl₂. This reaction is disturbed by AsO₃^3-.
