During the teaching process of ion polarization, the opposite and main contradictions in the theory of ion polarization were analyzed. Based on the opposition and unity in the contradictions, we described the mutual polarization. And then anti-polarization was introduced, which implied the complexity of the contradiction. At last, the limitations of the ion polarization theory were put forward by using the universality and particularity of the contradiction. Along these lines, we constructed a teaching model for ion polarization theory based on dialectical principle of contradiction. Assisted by the scientific teaching method combined with the typical examples, it is much easier for the students to grasp the core issues in ion polarization theory, which effectively counteracts the difficulties in learning the scattered knowledge points. It is essential to cultivate students' scientific thinking abilities. As one of the important philosophical category of Marxism, it also benefits for the cultivation of students' scientific ideological and political outlook.

Key words: Dialectical principle of contradiction, Ion polarization theory, Inorganic chemistry, Teaching method, Course ideology and politics
