3 moles of metal complex with formula Co ( en ) 2 Cl 3 gives 3 moles of silver chloride on treatment with excess of silver nitrate. The secondary valency of Co in the complex is (Round off to the nearest integer)

Correct answer

0

Step-by-step solution

3 Co ( en ) 2 Cl 2 Cl + AgNO 3  (excess) → 3 AgCl  (white ppt.  ) Secondary valency is equal to coordination number of Co = 6
