A saturated solution of `Ag_(2)SO_(4) is 2.5 xx 10^(-2)M`. The value of its solubility product is

Options

A. `62.5 xx 10^(-6)`
B. `6.25 xx 10^(-4)`
C. `15.625 xx 10^(-10)`
D. `3.125 xx 10^(-6)`

Answer

A

Explanation

`{:(Ag_(2)SO_(4) hArr,2Ag^(o+)+,SO_(4)^(2-)),(,2x,x):}`
`K_(sp) = 4x^(3) = 4 xx (2.5 xx 10^(-2))^(3) = 62.5 xx 10^(-6)`
