(X₂ ) is used in the refining of Ti metal by van Arkel method. (Y₂ ) does not liberate ( O ₂ ) from water and does not form ( HY ) and ( HOY ) with water. (X₂ ) and (Y₂ ) are respectively

Options

  1. A( I ₂, Cl ₂ )
  2. B( Cl ₂, I ₂ )
  3. C( I ₂, I ₂ )
  4. D( Cl ₂, Cl ₂ )

Correct answer

C. ( I ₂, I ₂ )

Step-by-step solution

Given, (X₂ ) is used for refining of Ti-metal using van Arkel method. Also (Y₂ ) does not give ( O ₂ ) from water and does not form ( HY ) and ( HOY ) with water. (X₂ ) and (Y₂ ) respectively. ( I ₂ ) is used for refining Ti metal using van Arkel method. Also when ( I ₂ ) reacts with ( H ₂ O ), it does not give ( O ₂ ) and does not form ( HI ) or ( HOI ). Therefore, both (X₂ ) and (Y₂ ) are ( I ₂ ). The reactions are given below: (i) ( Impure Ti +2 I ₂ TiI ₄ Ti +2 I ₂ ) (ii) ( I ₂+ H ₂ O IO ⁻+2 H ⁺+ I ⁻ ) Thus, opt
