Question

Which from following is NOT correct regarding electrolysis?

• A. It helps in refining of metals.
• B. Conversion of electrical energy into chemical energy takes place.
• C. It is useful in electroplating.
• D. Metal is deposited at anode.

Hint:

Remember the classic mnemonic: Red Cat (Reduction happens at the Cathode). Since gaining electrons to turn metal ions into solid metal atoms is a reduction process, it must happen exclusively at the cathode!

Answer 1

The Correct Option is D

Step 1: Recall electrode roles.
In electrolysis, positive metal ions move to the negative electrode, the cathode, and are reduced and deposited there.

Step 2: Check the statements.
Refining, electroplating, and turning electrical energy into chemical energy are all true uses of electrolysis.

Step 3: Spot the wrong one.
The statement that metal is deposited at the anode is false, since deposition happens at the cathode.
\[ \boxed{\text{Metal is deposited at anode, option 4}} \]
