Electrochemistry Revision: The Nernst Equation | Electrochemistry | CAIE A Level Chemistry 9701 (A2)

Revise electrochemical cells for CAIE A Level Chemistry: set up and label a cell, calculate E cell from data-booklet values, and use the Nernst equation to predict how concentration changes electrode potential. ▶ Try Alt Academy free: https://trial.altacademy.org/?utm_sou... A past-paper-based revision lesson on Electrochemistry for CAIE A Level Chemistry (9701). Bilal Hameed works through the cell and electrode potential question types that come up in recent exams, showing two reliable ways to get E cell and the reasoning examiners want for concentration changes. In this lesson • Labelling a cell with a standard hydrogen electrode, salt bridge and platinum electrode • Deciding which half-equation goes forward from the sign and size of E⦵ values • Identifying the positive and negative electrodes, anode, cathode and direction of electron flow • Calculating E cell two ways, and why you never multiply E⦵ when balancing equations • Using Le Chatelier's principle to explain how concentration changes an electrode potential • Applying the Nernst equation to calculate a non-standard electrode potential Chapters 0:00 Introduction: electrochemistry revision 1:06 Setting up and labelling a cell 8:22 Calculating the cell potential 14:54 Worked example: copper and iron(III)/iron(II) cell 18:22 Concentration effects and the Nernst equation Watch first ▶ Electrochemistry 1:    • Electrochemistry 1: Redox and Electrochemi...   — Alt Academy: courses in all major subjects across A Level, International GCSE and O Level.
