Answer: Option D. -> [Co(NH3)5Cl]Cl2
:
D
Two moles of AgCl with AgNO3 means that two ‘Cl’ atoms are ionisable. The third must be within the coordination sphere.
[Co(NH3)5Cl]Cl2→[Co(NH3)5Cl]2++2Cl−2AgNO3−−−−−→2NO−3+2AgCl

Answer: Option A. -> 86
:
A
The complex ion is [HgI4]2− and the metal ion is Hg2+
∴ E.A.N = 80 - 2 + 4(2) = 86.
:
A
The complex ion is [HgI4]2− and the metal ion is Hg2+
∴ E.A.N = 80 - 2 + 4(2) = 86.
