Trusted teacher: Lesson: Electrochemistry Duration: 60 minutes Grade Level: Advanced Science / Chemistry (IGCSE, A Level, IB) Main Objectives: By the end of this lesson, students should be able to: 1. Define electrochemistry and explain its importance. 2. Describe the difference between electrolytic and galvanic (voltaic) cells. 3. Write half-reactions and overall cell reactions. 4. Calculate standard electrode potentials and predict the direction of electron flow. 5. Understand practical applications of electrochemistry in everyday life. Lesson Outline / Brief Notes: 1. Introduction to Electrochemistry (10 minutes) Definition: Electrochemistry is the branch of chemistry that deals with the relationship between chemical reactions and electricity. Key Concept: Redox reactions involve the transfer of electrons. Real-life example: Batteries, electroplating, corrosion prevention. 2. Galvanic (Voltaic) Cells (15 minutes) Composed of two half-cells connected by a salt bridge. Oxidation occurs at the anode, reduction at the cathode. Example: Daniell cell Zn(s) | Zn2+(aq) || Cu2+(aq) | Cu(s) Oxidation: Zn → Zn2+ + 2e− Reduction: Cu2+ + 2e− → Cu 3. Electrolytic Cells (10 minutes) Require an external power source to drive non-spontaneous reactions. Example: Electrolysis of molten NaCl At cathode: Na+ + e− → Na At anode: 2Cl− → Cl2 + 2e- 4. Standard Electrode Potentials (10 minutes) Electrode potential measures the tendency of a species to be reduced. Example: Zn2+/Zn: -0.76 V Cu2+/Cu: +0.34 V Predict electron flow: Electrons flow from Zn to Cu in a Daniell cell. 5. Applications of Electrochemistry (5 minutes) Batteries (Li-ion, lead-acid) Electroplating (silver plating, chromium plating) Corrosion protection (galvanization) Exercise (10 minutes) 1. Short Answer Questions: a. Define electrochemistry. b. Identify the anode and cathode in a zinc-copper galvanic cell. c. Explain the difference between galvanic and electrolytic cells. 2. Calculation: Given: Zn2+/Zn: -0.76 V Cu2+/Cu: +0.34 V Calculate the standard cell potential of a Daniell cell. 3. Application Question: Describe one practical application of electrochemistry in everyday life and explain how it works.

Fleur surpassed expectations! In such a short span of time, she taught my 12-year-old how to draw croquis, conceptualize a collection, draping, and pattern-making. She then helped my daughter bring a dress design to fruition, from visiting a fabric store to select muslin, the right material and trims to sewing the garment to completion. Her patience and kindness every step of the way made my daughter feel comfortable and confident as she learned new skills. Fleur was always on time, very accommodating with her schedule and helped to make our visit in Paris a truly unique and memorable one.
