Electrochemistry: Standard Electrode Potentials and Redox Feasibility · Semester 1
Electrolysis: Faraday's Laws, Selective Discharge and Industrial Applications
Students will investigate the process of electrolysis, where electrical energy is used to drive non-spontaneous chemical reactions, and its basic applications.
Key Questions
- Apply Faraday's laws to calculate the mass of product deposited and the volume of gas evolved at each electrode during electrolysis, given current and time, ensuring dimensional consistency.
- Predict the products of electrolysis of a mixed aqueous electrolyte by applying selective discharge rules, justifying predictions using electrode potential data and the effect of ion concentration.
- Analyse the industrial electrolysis of brine (chlor-alkali process), explaining how electrode material choice and ion-exchange membranes control product selectivity and prevent cross-contamination.
