Question

Statement 1: The passage of an electric current through a conducting solution causes chemical reactions.
Statement 2: While testing a potato, the greenish blue spot is observed around the wire connected to the negative terminal of a cell.

• A. Statement 1 is true and statement 2 is false. ​
• B. Statement 1 is false and statement 2 is true.​
• C. Both the statements are true.​
• D. Both the statements are false.​

Answer 1

The correct option is A Statement 1 is true and statement 2 is false. ​

The passage of an electric current through a conducting solution causes chemical reactions. That may cause:
1. Change in colour of the solution.
2. Evolution of gases.
3. Deposition of metals.
Also, testing a potato is used to find terminals of a battery:

The greenish blue spot is always observed around the wire connected to the positive terminal of a cell.
Therefore, statement 1 is true and statement 2 is false.
