In this chemistry lab, students will explore the conductivity of various ionic and non-ionic compounds when submerged in deionized water. The objective is to identify which compound generates the largest current from the same battery. Students will analyze solutions including NaCl, CaF2, C8H18 (octane), and AlCl3, providing explanations supported by diagrams and equations. Collaboration in groups of three will foster engagement and deeper understanding of ionic dissociation and conductivity.
