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.

My journey : Origins & Languages: Originally from Sweden, I have lived in Paris for over ten years. Courses available in French, English and Swedish. Stage & Studio Experience: More than 15 years on the road and in the studio (rock, metal, blues, electro, etc.). Students Trained: More than 100 students, aged 12 to 71, with varied objectives (discovery, improvement, preparation for auditions, etc.). Method & Contents: Tailor-made courses: Adapted to your musical tastes (Beatles, Hendrix, Pink Floyd, John Mayer, Metallica, Slipknot...), your level and your objectives. Structured Follow-up: Google Doc shared after each session (notes, exercises, personalized backing tracks). Quick Learning: Targeted exercises to progress technically and musically. Improvisation: As soon as you know your first notes, we work on improvisation so that you can enjoy playing quickly. Home Studio & Recording: Professional Studio: Equipped with Pro Tools and Ableton Live. Recording Options: Learn how to record guitar and vocals. Walk away with tracks to practice or create your own. Why Choose Me? Concrete & Dynamic Approach: Drawn from my stage and studio experience. No Standardized Courses: Your motivation and your desires are at the heart of each lesson.

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.

Anders was able to assess my level and what I want to learn and adapted the lesson and material accordingly. It's easy to communicate with him and he has a lot of ideas to make it challenging enough to want to practise, but not too hard to follow. The experience was overall nice and enriching. The studio is well equipped and I liked the fact that he uses modern tools to send documents and tabs instead of paper. I definetly recommend.
