In the given reaction cycle X , Y and Z respectively are

Options

  1. AX - CaCO 3 ,   Y - NaCl ,   Z - KCl
  2. BX - CaCO 3 ,   Y - NaCl ,   Z - HCl
  3. CX - CaO ,   Y - NaCl + CO 2 ,   Z - NaCl
  4. DX - CaO ,   Y - NaCl + CO 2 ,   Z - KCl

Correct answer

B. X - CaCO 3 ,   Y - NaCl ,   Z - HCl

Step-by-step solution

When calcium chloride reacts with sodium carbonate, a double replacement reaction takes place. The products of this reaction are calcium carbonate and sodium chloride. CaCl 2 + Na 2 CO 3 → CaCO 3 X + 2 NaCl Y To Obtain Calcium chloride from Calcium carbonate we need to react calcium carbonate with Hydro chloric acid. CaCO 3 X + 2 HCl Z → CaCl 2 + CO 2 g + H 2 O l ∴   ( X )   CaCO 3 ( Y )   NaCl ( Z )   HCl
