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.

- **Physics**: Physics is a natural science that studies matter, energy, motion, and the interactions between them. It seeks to understand the fundamental laws that govern the universe, whether at the subatomic, atomic, macroscopic, or cosmological scale. Physics covers a wide range of fields, from classical mechanics to quantum physics to astrophysics and particle physics. - **Mathematics**: Mathematics is a fundamental discipline that deals with abstract quantities, shapes, structures, and relationships. It is used to formulate models, solve problems, predict phenomena, and explore abstract concepts. Mathematics includes fields such as algebra, geometry, calculus, number theory, statistics, logic, and many others, and is essential in many scientific and technical fields. - **Chemistry**: Chemistry is the science that studies the composition, structure, properties, and transformations of matter. It examines chemical elements, compounds, and the chemical reactions that occur between them. Chemistry is present in many aspects of everyday life, from biological reactions to the synthesis of new materials to understanding environmental phenomena. The different fields of chemistry include organic, inorganic, analytical, physical, and biochemical chemistry.

Graduated in Mathematics, I have more than 6 years of experience giving support courses in Mathematics, and Physics/Chemistry for all levels up to the final year (Bac). As I was a tutor in colleges for homework help. I may provide refresher courses, intensive courses to prepare candidates for the brevet and baccalaureate, as I know all the school programs. I am seriously invested in passing on my knowledge and attributing it to the academic success of the students I support, with good monitoring and reports for parents at the end of each class session.

School coach in science subjects Experienced math teacher and school coach offers HOME SUPPORT COURSES: MATHS, SVT, PHYSICS CHEMISTRY. My approach After carrying out an assessment with the child and their parents, I propose a personalized academic support program. This means that each course is adapted to each student according to their level, their situation, their motivation and their way of perceiving things. I listen to the student and their needs, I give them confidence in their abilities, I communicate to them the taste and desire to learn and progress. I coach students and parents with a positive and caring but effective approach. What I propose Courses adapted to the child's needs and objectives Preparation for the brevet and baccalaureate exams, refresher training, advanced training Educational coaching, assessment, intensive training, pre-entry, regular monitoring My results I can turn a student who is very behind and unmotivated into a student who obtains the baccalaureate or the brevet with ease. And for a student who is motivated but lacks method, I can make him achieve excellence. I often accompany siblings and my students regularly recommend me to their friends. References from satisfied students and parents available upon request. My particularity I have good experience with children, adolescents with special needs such as gifted children or those with dyslexia. I gladly accept CESU.

Hello, My name is Redouane and I am a student in physical chemistry. I obtained a bac S with honors, then a bachelor's degree in general chemistry and a master's degree in physical chemistry at the University of Paris Saclay. Maths and physics chemistry are my favorite subjects. However, I am also able to help with homework in scientific and literary subjects (French, history, geography or English). I am bilingual in English and able to have conversations on any subject. I am a meticulous and patient person. I like the pedagogy and pass on my knowledge to the youngest. I am available weekdays and weekends. My price corresponds to my level of diploma while remaining accessible to a maximum of people. The right to understand and to be successful must be accessible to everyone.

After taking preparatory classes at the Lycée Henri IV (Paris) in the PCSI-PC * stream, I joined the Ecole Normale Supérieure de Lyon. I teach Mathematics, Physics and Chemistry from the second to the first year of preparation. Out of habit, I first focus this tutoring on a perfect mastery of the course then on the resolution of "standard" exercises, classic allowing to re-use as well as possible the concepts approached in the course.

Associate Professor of Life and Earth Sciences, holder of a master's degree from Paris Sud University, I teach courses in all scientific subjects for primary, college and high school students. During the first session, I establish with the student a revision program adapted to the degree of intensity and the working time that he wishes. This goes from the one-off course to the very intensive program with a view to close deadlines (patent, bac, entrance examination to grandes écoles, BEP).

In this course I will explain mathematical and physical concepts in a natural and intuitive way while encouraging the student to participate during the course. Because personally, I think our school system intimidates people who want to do math or physics with stereotypes that are not totally true.

math will help you de-stress. Math teaches you to analyze the situation well before making a decision and taking action, it intervenes in all areas of life, it is the basis of science in my opinion In France, nearly 2.4 million jobs depend on mathematics. Indeed, many areas require to be good at math. From science to medicine, from the economy to the environment, including new technologies and public decision-making, mathematics is everywhere
