Which of the following statements is correct regarding the cathode of electrochemical cell ?
Show Hint
- Oxidation occurs at the cathode
- Reduction occurs at cathode
- Usually denoted by a negative sign
- Is usually made up of non conducting material.
The Correct Option is B
Solution and Explanation
Use the mnemonic 'RED CAT': reduction at the cathode.
Step 2: Result:
Statements A, C and D contradict this and the basic nature of electrodes, so only B is true.
Final Answer:
Reduction occurs at the cathode, option (B). \[ \boxed{\text{Reduction occurs at cathode}} \]
