Critical micelle concentration for a soap solution is 1.5xx10^(-4) mol L^(-1) .Micelle formation is possible only when the concentration of soap solution in mol L^(-1) is

Answer»

`2.0 xx 10^(-3)`
`4.6 xx 10^(-5)`
`7.5 xx 10^(-5)`
`1.1 xx 10^(-4)`

Solution :(a): Micelles FORMATION takes PLACE above the critical micelle concentration which is `1.5 xx 10^(-4)` mol `L ^(-1)` (GIVEN). Therefore, micelle formation is POSSIBLE only when the concentration of soap solution will be` 2.0 xx 10^(-3)` mol `L^(-1)`.
