Assertion : Magnesium is extracted by the electrolysis of fused mixture of MgCl ₂, NaCl and CaCl ₂ . Reason : Calcium chloride acts as a reducing agent.

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

C. If assertion is true but reason is false.

Step-by-step solution

NaCl and CaCl ₂ are added to provide conductivity to the electrolyte and also to lower the fusion temperature of anhydrous MgCl ₂ .
