This article presents a chemical experiment and learning activities for understanding the reactivity of metal ions using pigments. Reliable methods for identification of metal ions in pigment samples such as Pb^<2+>, Cu^<2+>, Cd^<2+>, Fe^<3+>, Zn^<2+>, and Cr^<3+> ions are described. These methods also improve the procedure for small-scale experiments to become available more easily in high school chemistry courses. On the basis of the above findings, we propose two types of learning activities. One is a hands-on activity through which high school students can realize the reactivity of metal ions when they are studying, or have just studied, inorganic chemistry. The other is an inquiry-based learning activity which enables students to draw a conclusion on "what metal ion is found in given pigment samples" by utilizing their previous knowledge. These activities not only promote students' conceptual understanding of inorganic chemistry, but also more sophisticated scientific thinking about design, practice, and verification of their experiments.
