Introduction to Electrochemistry—
Student Laboratory Kit
By: The Flinn Staff
Introduce the basic principles of electrochemistry with this introductory level experiment. What happens when an electric current flows through water? How does electricity cause chemical reactions to occur? Students build simple electrochemical cells using a Petri dish, pencil leads, and a 9-volt battery, and then investigate the chemical reaction that occurs when current is forced through water. By comparing the amount of gas and indicator color changes at each electrode, students identify indi- vidual reactions that occur and determine the overall chemical reaction. This safe and economical experiment is also a great “classifying matter” activity to prove water is a compound. Includes reproducible student handouts, detailed background information and Instructor’s Notes with sample data and answers to all questions.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students working in pairs. 9-V batteries are required and available separately.

Electrolysis Reactions— Student Laboratory Kit By: The Flinn Staff
Build a simple electrochemical cell using a partitioned Petri dish and carbon (pencil lead) electrodes to investigate electrolysis reactions in the lab. When an electric current is passed through an aqueous solution containing sodium sulfate, an electrolyte, the water molecules decom- pose to give oxygen and hydrogen gas. What happens if the electrolyte contains ions that are more easily oxidized or more easily reduced than water molecules? Use this safe and economical activity to determine the products obtained in the electrolysis of aqueous potassium iodide, copper(II) bromide, and sodium chloride solutions. The oxidation and reduction half-reactions are identified by comparing the indicator color changes, amount of gas, and reactivity of the products generated at each electrode. This kit is a great way to explore the historical and industrial importance of electrolysis, from the discovery of the alkali metals to the production of aluminum. Includes reproducible student handouts, detailed background information, complete Instructor’s Notes with sample data and answers to all questions, and all necessary chemicals and consumable supplies.
Complete for 30 students working in pairs. Super Value Kit is complete for 5 classes of 30 students in working pairs. 9-V batteries and battery clips with alligator clip leads are needed and available separately.
