Coordination Compounds Question 7
Question 7 - 25 January - Shift 2
Total number of moles of $AgCl$ precipitated on addition of excess of $AgNO_3$ to one mole each of the following complexes $[Co(NH_3)_4 Cl_2] Cl$, $[Ni(H_2 O)_6] Cl_2,[Pt(NH_3)_2 Cl_2]$ and $[Pd(NH_3)_4] Cl_2$ is
Show Answer
Answer: (5)
Solution:
Formula: Werners theory
$[Co(NH_3)_4 Cl_2] Cl \Rightarrow$ Gives 1 mole $AgCl$
$[Ni(H_2 O)_6] Cl_2 \Rightarrow$ Gives 2 moles $AgCl$
$[Pt(NH_3)_2 Cl_2] \Rightarrow$ Gives No AgCl
$[Pd(NH_3)_4] Cl_2 \Rightarrow$ Gives 2 moles $AgCl$
Total number of moles of $AgCl=5$ mole
