The K_(sp) of Ag_(2) CrO_(4) is 1.1xx10^(-12)at 298 K. Thesolubility (in mol/L) of Ag_(2)CrO_(4) in 0.1 MAgNO_(3) solution is

Answer»

`1.1xx10^(-11)`
`1.1xx10^(-10)`
`1.1xx10^(-12)`
`1.1xx10^(-9)`

Solution :`{:(Ag_(2)CrO_(4),hArr,2"Ag"^(+),+,CrO_(4)^(-)),(s,,2s+0.1,,s),(,,(0.1 "from AgNO"_(3)),,),(,,~= 0.1 M,,),(,,"(as sis negligible incomparison to 0.1)",,),(,,,,):}`
`K_(SP)=[Ag^(+)]^(2)[CrO_(4)^(2-)]`
`1.1xx10^(-12)= (0.1)^(2)XXS or s=1.1xx10^(-10)M`
