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^(-6)`
D. `3.125 xx 10^(-6)`

Answer

A

Explanation

`{:("For",AgSO_(4)rarr,2Ag^(+)+,SO_(4)^(-)),(,,2x,x):}`
`K_(sp) = (2x)^(2).x , K_(sp) = 4x^(3) , K_(sp) = 4 xx (2.5 xx 10^(-2))^(3)`
`K_(sp) = 62.5 xx 10^(-6)`.
