Assertion : `[Co(NH_(3))_(5)Br]SO_(4)` gives white precipitate with barium chloride .
Reason : The complex `[Co(NH_(3))_(5)Br]SO_(4)` dissociates in the solution to give `Br^(-)` and `SO_(4)^(2-)`.
A. If both Assertion and reason are true and reason is the correct explanation of assertion
B. If both assertion and reason are true but reason is not the correct explanation of assertion
C. If assertion is true but reason is false
D. if both assertion and reason are false

Correct Answer - C
The complex `[Co(NH_(3))_(5) Br]SO_(4)` dissociates to give `[Co(NH_(3))_(5)Br]^(2-)` and `SO_(4)^(2-)` ions . `SO_(4)^(2-)` ion reacts with barium chloride to give white ppt. of `BaSO_(4)`,
`SO_(4)^(2-) + BaCl_(2) to BaSO_(4) + 2 Cl^(-)`
