At a certain temperature, the solubility of the salt `A_(x)B_(y)` is S moles per litre. The general expression for the solubility product will be

A

`K_(sp)=X^(y)Y^(x)S^(x+y)`

B

`K_(sp)=(XY)^(x+y)S^(x+y)`

C

`K_(sp)=(X^(x)Y^(y))S^(x+y)`

D

`K_(sp)=X^(y)Y^(x)S^(xy)`

Text Solution

Verified by Experts

The correct Answer is:
C
`A_(x)B_(y)(s)hArr xA^(y+)(aq.)+yB^(x-)(aq.)`
`K_(ap)=C_(A^(y+))^(x)C_(B^(x-))^(y)`
`= (xS)^(x)(yS)^(y)`
`= (x^(x)S^(x))(y^(y)S^(y))`
`x^(x)y^(y)S^(x+y)`
