The solubility product of a binary weak electrolyte is 4 xx 10^(-10) " at"298K. It's solubility in mol dm^(-3) at the same temperature is

Answer»

`8 xx 10^(-10)`
`16 xx 10^(-20)`
`4 xx 10^(-5)`
`2 xx 10^(-5)`

SOLUTION :For binary electrolyte the solubility and solubility product RELATION is `K_(SP) = S.S`.
`S= sqrt(K_(SP)) = sqrt(4 xx 10^(-10)) = 2.10^(-5) mol dm^(-3)`
