Oxidation number of the metal ion in the compound [CO(NH_(3))_(5)Cl]Cl_(2) is +3. Calculate the oxidation number of the complex ion.

Answer»

SOLUTION :Chlorine present outside the complex coordination sphere are chloride ions.
Since there are two `CL^(-)` ions outside, the OXIDATION number of complex ion is +2.
The ion is givne as `[CO(NH)_(3))_(5) Cl]^(2+)`
