Solubility of BaF(2) in a solution of Ba...

Solubility of `BaF_(2)` in a solution of `Ba(NO_(3))_(2)`, will be represented by the concentration term:

A

`[Ba^(2+)]`

B

`[F^(-)]`

C

`1//2[F^(-)]`

D

`2[NO_(3)^(-)]`

Text Solution

Verified by Experts

The correct Answer is:
C
Let S is the solubility of `BaF_(2)` in a solution of `BaNO_(3)`,
Then `K_(SP)=[Ba^(2+)][F^(-)]^(2)`,
Then `[F^(-)]=2S`,
Then `(1)/(2)[F^(-)]=S`

The solubility of CaF_(2) in a solution of 0.1M Ca(NO_(3))_(2) is

The solubility product of a soluble salt A_(x)B_(y) is given by: K_(SP)= [A^(y+)]^(x) [B^(x-)]^(y) . As soon as the product of concentration of A^(y+) and B^(x-) increases than its K_(SP) , the salt start precipitation. It may practically be noticed that AgCI is more soluble in water and its solublity decreases dramatically in 0.1M NaCI or 0.1M AgNO_(3) solution. It may therefore be conncluded that in presence of a common ion, the solubiolity of salt decreases. Which of the following statement is wrong ? (1) K_(SP) of a salt depends upon temperature (2) K_(SP) of a salt has no units (3) The K_(SP) of salt A_(x)B_(y) can be given as: x^(x).y^(y)(S)^(x+y) (4) Solubility of BaF_(2) in a solution of Ba(NO_(3))_(2) can be given by (1)/(2)[F^(-)]
