**Electrolysis of Molten Chromium Bromide (CrBr₃)** **Question Prompt:** Answer questions 5-8 for the electrolysis of molten chromium bromide (CrBr₃) as seen in the diagram below. **Diagram Explanation:** The diagram illustrates the setup for the electrolysis of molten chromium bromide (CrBr₃). - **Container:** The reaction takes place in a container filled with molten CrBr₃. - **Electrodes:** - **Anode:** The electrode on the left is labeled as the anode, where oxidation occurs. Bubbles indicate gas formation at this site. - **Cathode:** The electrode on the right is labeled as the cathode, where reduction occurs. Bubbles also indicate gas formation here. - **Porous Screen:** A porous screen separates the two halves of the apparatus, preventing the products from reacting with each other. - **Voltage Source:** A voltage source is connected to the electrodes, driving the electron flow (e⁻) from the anode to the cathode. The anode is connected to the positive terminal, and the cathode to the negative terminal. - **Electron Flow:** The flow of electrons is shown by arrows pointing from the anode towards the cathode via the external circuit. This setup is used to break down CrBr₃ into its constituent elements through the application of electrical energy.
