A) \[[Co{{(N{{H}_{3}})}_{5}}Cl]C{{l}_{2}}\]
B) \[[Co{{(N{{H}_{3}})}_{4}}C{{l}_{2}}]Cl\]
C) \[[Co{{(N{{H}_{3}})}_{3}}C{{l}_{3}}]\]
D) \[[Co{{(N{{H}_{3}})}_{6}}]C{{l}_{3}}\]
Correct Answer: A
Solution :
[a] :\[\Delta {{T}_{f}}={{K}_{f}}\times i\times m\] \[0.0558=1.86\times i\times 0.01\Rightarrow i=3\] Given complex is a strong electrolyte. For strong electrolyte, i = n n = No. of ions = 3 ions Therefore, formula of the complex is \[[Co{{(N{{H}_{3}})}_{5}}Cl]C{{l}_{2}}\].You need to login to perform this action.
