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)
