The charges x and y on the following ion...

The charges x and y on the following ions are
`(i) [Co(NH_(3))_(2) Cl_(4)]^(x) " " (ii) [Fe(CN)_(6)]^(y)`
(Oxidation state of Co is +3 and Fe is + 2 in their respective complexes.)

A

x = + 1 , y = - 1

B

x = -1 , y = + 3

C

x = -1 , y = -4

D

x = -2 , y = -3

Text Solution

Verified by Experts

The correct Answer is:
C
In `[Co(NH_(3))_(2) Cl_(4)]^(x)` , oxidation state of Co = + 3
Hence , x = `+ 3 + 2 xx 0 + 4 xx (-1) = -1`
In `[Fe(CN)_(6)]^(y)` , oxidation state is the residual charge on the central metal atom left after removing all ions .
