Calculate the oxidation state of central metal atom in
(i) `[Co(NH_(3))_(5)Cl]^(2+)`
(ii) `K_(4)[Fe(CN)_(6)]`
(iii) `[Co(NO_(2))_(2)(py)_(2)(NH_(3))_(2)]NO_(3)`

Text Solution

Verified by Experts

(i) `[Co(NH_(3))_(5)Cl]^(2+)`
`x+5 xx (0) + (-1)=+2,` or `x=3`,
Oxidation state of `Co= +3`
(ii) `K_(4)[Fe(CN)_(6)]`
`4xx(1) + x + 6(-1)=0, or x=2`,
Oxidation state of `Fe= +2`
(iii) `[Co(NO_(2))_(2)(py)_(2)(NH_(3))_(2)]NO_(3)`
`x+2(-1)+2xx(0)+2xx(0)+(-1)=0`, or `x=3`,
Oxidation state of `Co=+3`
