On the addition of a solution containing CrO_(4)^(2-) ions to the solution of Ba^(2+), Sr^(2+) and Ca^(2+) ions, the precipitate obtained first will be of

Answer»

`CaCrO_(4)`
`SrCrO_(4)`
`BaCrO_(4)`
MIXTURE of (a), (b), (c)

Solution :When we added barium ion in chromate ion solution we obtained YELLOW ppt of `BaCrO_(4)`.
`BaCl_(2)+ K_(2)CrO_(4) rarr underset("Yellow ppt".)(BaCrO_(4)) darr + 2KCl`
