Question
For finding the oxidation state of metal atom in coordination compound, charge on the ligand should be known.
Chloro ligand has -1 charge. amino ligand is neutral.
[MnCl2(NH3)4]*
Let x is the oxidation state of metal. Above compound has +1 charge on it
x+2(-1)+4(0) = 1
x-2+0=1
x =1+2= 3
So, oxidation of Mn metal = 3
[Co(CN)4(H20)2]²-
x+ 4(-1) + 2(0) = -2
x= -2 +4 = 2
Oxidation state of Co metal = 2
[Fe(OH)sCO]3-
x+5(-1) + 0 = -3
x - 5 = -3
x= -3 +5= 2
So, oxidation state of Fe metal = 2
