A solution containing 2.675g of CoCI3.6NH3 (molar mass=267.5 g mol-1) is passed through a cation exchanger. Thechloride ions obtained in solution were treated with excess of AgNO3 to give 4.78 g of AgCI (molar mass = 143.5 g mol-1). The formula of the complex is:
(At. mass of Ag =108 u)
  • a)
    [CoCI(NH3)5]CI2    
  • b)
    [Co(NH3)6]CI3    
  • c)
    [CoCI2(NH3)4]CI
  • d)
    [CoCI3(NH3)3]
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
A solution containing 2.675g of CoCI3.6NH3 (molar mass=267.5 g mol-1) ...
Meq. of Cl- CIoutside the sphere
 
= 0.033 mole of CI-
∴ WCl = 1.1825g
  or 0.01 mole of complex gives 0.01 x n mole of Cl-
 ∴ 0.01 x n = 0.033 ∴ n = 3
Thus, formula is [Co(NH3)6]CI3
