If the concentration of lead iodide in its saturated solution at 25^(@)C be 2 xx 10^(-3) moles per litre, then the solubility product is

Answer»

`4 xx 10^(-6)`
`8 xx 10^(-12)`
`6 xx 10^(-9)`
`32 xx 10^(-9)`

SOLUTION :`{:(PbI_(2) ,HARR,(Pb^(++)), + ,(2I^(-))),(,,S,,2S):}`
`K_(sp) = 4S^(3) = 4 xx [2 xx 10^(-3)]^(3) = 32 xx 10^(-9)`.
