The correct Answer is:
To solve the question "................. is connected to the negative terminal of the battery," we need to identify which component is typically connected to the negative terminal in an electrochemical cell. ### Step-by-Step Solution: 1. **Understand the Components of a Battery**: - A battery has two terminals: a positive terminal and a negative terminal. - These terminals are connected to electrodes in an electrochemical cell. 2. **Identify the Electrodes**: - There are two types of electrodes: the anode and the cathode. - The anode is where oxidation occurs, and it attracts anions (negatively charged ions). - The cathode is where reduction occurs, and it attracts cations (positively charged ions). 3. **Determine the Charge of the Electrodes**: - The cathode is negatively charged because it attracts positively charged cations. - The anode is positively charged because it attracts negatively charged anions. 4. **Connect the Dots**: - Since the question states that something is connected to the negative terminal of the battery, and we know that the cathode is negatively charged, it follows that the cathode is the component connected to the negative terminal. 5. **Final Answer**: - Therefore, the answer to the question is: **"Cathode is connected to the negative terminal of the battery."**
