Answer» Correct Answer - A If `K_(sp)` is `3.2 xx10^(-17)` In pure water `K_(sp)=4s^(3)=32xx10^(-18)` `s_(4)=2xx10^(-6)` in `NH_(3)` solubility increases due to complex formation. ln 0.1M `AgNO_(3)` `Ag_(2)CrO_(4)iff2Ag^(+) + CrO_(4)^(-2)` `2S_(2)+0.1 " "S_(2)` `S_(2)=32 xx 10^(-18)` `ln 0.2 M" "K_(2)CrO_(4)` `Ag_(2)CrO_(4)iff2Ag^(+)+CrO_(4)^(-2)` `2S_(1)" "S_(1)+0.2` `3.2 xx10^(-17)=4S_(1)^(2)` `16xx10^(-17)=4S_(1)^(2)` `S_(1)=6.5 xx10^(-9)` |
