`X_(3)B_(3)(AlF_(6))_(2)` की मोलर विलेयता 298 K पर है x विलेयता गुणनफल `K_(sp)` है

Options

A. `18 x^(3)`
B. `27x^(4)`
C. `27x^(8)`
D. `2916x^(8)`

Answer

D

Explanation

`X_(3)B_(3) (AlF_(6))_(2) hArrunderset (3x)3X+underset(3x)3B+underset(2x)2AlF_(6)`
`K_(sp) = [X]^(3) [B]^(3)[AlF_(6)]^(2)`
`= (3x)^(3)(3x)^(3) (2x)^(2)`
` = (27x^(3)) (27x^(3)) (4x^(2)) = 29916 x^(B)`
