Question

Boojho made the circuit shown in Fig. 14.10. What happens when he forgot to add a few drops of lemon juice to water ?

• A. a large amount of current flow in the circuit.
• B. color change of water.
• C. heat produce.
• D. No current pass through the circuit.

Answer 1

Answer: (D)

No current pass through the circuit.

If Boojho has taken distilled water as the electrolytic solution and has forgotten to add lemon juice, then no current will pass through the circuit. This is because distilled water does not contain any dissolved salts in to conduct electricity. If the water taken is salty, then a feeble current will pass through the circuit and bubbles will be seen on the negative electrode.
