Assertion : In electrolysis, the quantity of electricity needed for depositing 1 mole of silver is different from that required for 1 mole of copper. Reason : The molecular weights of silver and copper are different.

Options

  1. AIf both assertion and reason are true and reason is the correct explanation of assertion.
  2. BIf both assertion and reason are true but reason is not the correct explanation of assertion.
  3. CIf assertion is true but reason is false.
  4. DIf both assertion and reason are false.

Correct answer

B. If both assertion and reason are true but reason is not the correct explanation of assertion.

Step-by-step solution

Ag ⁺+e⁻ Ag , Cu ²⁺+2 e⁻ Cu For deposition of Ag , 1 mole of electrons is required while for Cu , 2 moles of electrons are required. So quantity of electricity needed for depositing is different.
