Electrode Potentials and Electrochemical Cells (AQA)

4 Full Lesson Bundle which covers the AQA A Level Chapter on Electrode Potentials and Electrochemical Cells

Learning Objectives:

Lesson 1: Standard Electrode & Cell Potentials (Part 1)

LO1: To describe techniques and procedures used for the measurement of :

i) Cell potentials of metals or non-metals in contact with their ions in aqueous solution
ii) Ions of the same element in different oxidation states in contact with a Pt electrode

Lesson 2: Standard Electrode & Cell Potentials (Part 2)

LO1: To use the term standard electrode potential E⦵ including its measurement using a hydrogen electrode
LO2: To construct conventional representations of electrochemical cells
LO3: To calculate a standard cell potential (EMF) by combining two standard electrode potentials
LO4: To predict the feasibility of electrode potentials to modern storage cells

Lesson 3: Limitations of Cell Potentials

LO1. To understand the limitations of predicting the feasibility of a reaction using cell potentials due to kinetics and non-standard conditions

LO2. To explain why electrochemical cells may not work based on the limitations of using cell potentials

Lesson 4: Storage & Fuel Cells

LO1: To understand the application of the principles of electrode potentials to modern storage cells

LO2: To explain that a fuel cell uses the energy from a reaction of a fuel with oxygen to produce a voltage

LO3: To derive the reactions that take place at each electrode in a hydrogen fuel cell

The teacher will be able to check students have met these learning objectives through starter activities, discussion questions, mini AfL tasks and practice questions for students to complete

Declaimer: Please refrain from purchasing this popular resource for an interview lesson or a formal observation. This is because planning your own lessons, including using your own lesson PowerPoints, is a fundamental skill of a qualified/unqualified teacher that will be assessed during the scenarios outlined above
