**Transcription for Educational Website:****Title: Understanding Electrochemical Reactions****Instruction:**Identify the reaction that occurs at the anode and the cathode.**Interactive Dropdown Menus:**- **Anode:** - [Dropdown menu with selection options]- **Cathode:** - [Dropdown menu with selection options]---**Description:**This interactive module allows students to select and identify the specific electrochemical reactions occurring at the anode and cathode. By choosing from the dropdown menus, students can test their knowledge of the different reactions that typically occur at these electrodes in an electrochemical cell. **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.
