Summary: Lesson one demonstrates the circumstances under which common materials, such as sugar and table salt, conduct electricity. The process of electrolysis is demonstrated in the making of metallic leaves. In investigating the movement of ions, permanganate ions spread toward the anode side of a liquid chamber when electricity is applied. Lesson two demonstrates the formation of a metallic copper...
