Question

Which of the following complex will give white ppt. with `BaCl_(2)` solution ?
A. `[Co(NH_(3))_(4)SO_(4)]NO_(2)`
B. `[Cr(NH_(3))_(5)SO_(4)]Cl`
C. `[Cr(NH_(3))_(5)Cl]SO_(4)`
D. Both (b) and (c )

Answer 1

Correct Answer - C
`[Cr(NH_(3))_(5)Cl]SO_(4) rarr [Cr(NH_(3))_(5)Cl]^(2+)+SO_(4)^(2-)`
`[Cr(NH_(3))_(5)Cl]^(2+)+SO_(4)^(2-)+BaCl_(2) rarr [Cr(NH_(3))_(5)Cl]Cl_(2)+BaSO_(4)+HCl`
