Product Details

Why do single replacement reactions occur in one direction only, with a more active metal always replacing the ion of a less active metal? A ranking of metals based on their relative reactivity and ease of oxidation is called an activity series. In this microscale experiment, students carry out a series of possible single replacement reactions of copper, iron, magnesium, and zinc with solutions of metal cations. Analyzing the results allows students to rank the metals from most active to least active, determine the activity series of the metals, and predict the reactivity of metals that were not tested. The experiment also provides valuable practice writing chemical equations. Versatile student lab kit may be used to teach a variety of concepts—single replacement reactions, molecular versus net ionic equations, oxidation–reduction reactions, and activity series! Includes reproducible student handouts, detailed background information, complete Teacher Notes with sample data and answers to all questions, and all necessary chemicals and consumable supplies. Complete for 30 students working in pairs. Fifteen reusable 24-well reaction plates are recommended and available separately.
