The solubility of a substance in ether is 2.0 xx10^(-3)M .The distribution coefficient of the substance in ether - water mixture is 4. The solubility of the substance in ether is

Answer»

`3.0xx10^(-4)M`
`5.0xx10^(-4)M`
`6.0xx10^(-4)M`
`8.0xx10^(-4)M`

SOLUTION :`("Solubility in ether")/("Solubility in WATER")="K(distribution COEFF.)"therefore""(2xx10^(-3)M)/(S)=4 "or"S=5xx10^(-4)M`
