In this lab experience, students carry out an investigation to identify the ionic compounds, from a group of eight compounds, based on the compounds’ physical properties. Students come to understand that a material’s physical properties, such as melting point, are linked to the material’s structure and bonding. Moreover, ionic bonds tend to be strong and so ionic compounds tend to melt at relatively high temperatures.

Safety: Before conducting the lab, review with the class the safety precautions on the student page. Remind students to take care when conducting melting point tests as these require use of an open flame. Good ventilation is required since burning samples can generate smoke. Students should wear chemical splash goggles throughout the experiment.
