Write the relationship between K_(sp) and S of an AB_(2) type of salt. |
|
Answer» Solution :Consider an electrolyte `AB_(2)`, whose solubility is S mol `dm^(-3)`. In a saturated solution, `AB_(2(s))hArrA^(2+)+2B^(-)` `THEREFORE[A^(2+)]=S" mol "dm^(-3)and(B^(-))=2S" mol "dm^(-3)` `K_(sp)=[A^(2+)][B^(-)]^(2)=S:(2S)^(2)=4S^(3)` `thereforeK_(sp)=4S^(3)`. |
