Electrochemistry

Assignment-1 1. How does the electrode potential change with ion concentration according to the Nernst equation in a battery? 2. Why is calibration needed when using a glass electrode for pH measurement in industry? 3. Explain the factors affecting uniform coating in gold electroplating and suggest methods to improve plating quality (Case Study: A manufacturer notices uneven gold plating on electronic connectors, with rough patches and inconsistent thickness). 4. What are the problems associated with using a Calomel electrode as a reference electrode, and what alternatives can be used in industry? (Case Study: A laboratory is using a Calomel electrode as a reference for electrochemical measurements, but faces potential drift and safety concerns due to mercury)

Energy storage devices

Compare and critically analyze Lead-Acid Battery and Lithium-Ion Battery with respect to their working principle, electrochemical reactions, energy density, efficiency, lifespan, maintenance, and recyclability. Based on your analysis, recommend which battery is more suitable for electric vehicle and renewable energy applications, providing scientific justification for your choice.
