【Abstract】 The paper introduced how to develop a new creative experiment that combined both Organic chemistry and Analytical Chemistry experiments. In this experiment, we synthesized the inorganic ion chromogenic agent 7- (4-Antipyringlazo) -8-Hydroxyquinoline by diazotization-coupling reaction and elaborate on the researching method and the content of color development reaction between iron and this spectrophotometric reagent. Then investigated the necessity and feasibility of this experiment synthesizing 7-(4-Antipyringlazo)-8-Hydroxyquinoline and its color development reaction with iron. This experiment will help students improve their creative thinking and practical ability.更多还原
