1.	In a saturated solution of the sparingly soluble strong electrolyte. AgIO_(3) (molecular mass = 283), the equilibrium which sets in is :AgIO_(3)(s)hArr Ag^(+)(aq)+IO_(3)^(-)(aq)If the solubility product constant, K_(sp) of AgIO_(3)at a given temperature is 1.0xx10^(-8), what is the mass of AgIO_(3) contained in 100ml of its saturated solution ?
Answer» `2.83xx10^(-3)g` `1.0xx10^(-7)g` `1.0xx10^(-4)g` `28.3xx10^(-2)g` Solution :`AgIO_(3)(s)hArr Ag^(+)(aq)+IO_(3)^(-)(aq)` Let the solubility of `AgIO_(3)` in a saturated solution = s `K_(sp)=[Ag^(+)][IO_(3)^(-)]=s xx s =s^(2)` or `s=sqrt(K_(sp))=sqrt(1.0xx10^(-8))=10^(-4)mol L^(-1)` Concentration `=10^(-4)xx 283 g L^(-1)` or`=(10^(-4)xx283xx100)/(1000)` `=2.83xx10^(-3)` g per 100 ml .
