Which of the following statement(s) is/are correct?
Micelle formation by soap in aqueous solution is possible at all temperatures.
Micelle formation by soap in aqueous solution occurs above a particular concentration.
On dilution of soap solution micelles may revert to individual ions.
Both (2) and (3)
Answers (1)
Micelles are relatively small, spherical structures composed of a few to few thousand molecules that attract one another to form larger aggregate which falls in colloidal range.
Micelles are formed by aggregation of small molecules. Thus, they are also known as associated colloids.
Eg. Soap in water.
The formation of micelles takes place only above a particular temperature called Kraft temperature (Tk) and above a particular concentration called critical micelle concentration (CMC).
At low concentration, associated colloids behave as strong electrolyte whereas at high concentration, they behave as colloidal particle. This behaviour is due to the formation of aggregates.
Hence, on dilution of soap solution micelles may revert to individual ions.
Hence option 4 is correct.
