OB: redox class #3 Lots more practice with voltaic cells

This practice guide focuses on setting up standard voltaic cells and labeling essential components such as the anode, cathode, oxidation and reduction sides, as well as electron flows and ion movements. It includes exercises on writing half oxidation and half reduction reactions, along with net ionic equations for various solutions including sodium iodide, rubidium fluoride, barium nitrate, strontium hydroxide, and silver hydrogen carbonate. Mastering these concepts is vital for understanding electrochemical reactions in voltaic cells.

  1. OB: redox class #3Lots more practice with voltaic cells Starting with a standard issue voltaic cell set up, label it as shown in the next slide, show all the moving parts: oxidation side, reduction side, electron flow, solution charges, salt ion movement to offset solution charges, label anode and cathode, write half oxidation and half reduction reactions, write net ionic equation too.
