Which of the following options are correct?a)Micelle formation by soap...
Explanation:
When soap is added to water, it forms a colloidal solution. The soap molecules arrange themselves in a certain way in water, which is called micelle formation. The correct options are:
a) Micelle formation by soap in aqueous solution occurs above a particular concentration:
This is true because soap molecules arrange themselves in micelles only above a particular concentration, which is known as the critical micelle concentration (CMC). Below this concentration, soap molecules exist as individual ions.
b) Soap solution behaves as a normal strong electrolyte at all concentrations:
This statement is incorrect. Soap solution behaves as a weak electrolyte because it does not dissociate completely into ions in water.
c) On dilution of soap solution micelles may revert to individual ions:
This is true. On dilution of soap solution, the concentration of soap molecules decreases, and the micelles may revert to individual ions.
d) Micelle formation by soap in aqueous solution is possible at all temperatures:
This statement is incorrect. The formation of micelles by soap depends on various factors, including temperature, pH, and the presence of certain ions.
In summary, micelle formation by soap in aqueous solution occurs above a particular concentration, and on dilution of soap solution, micelles may revert to individual ions. Soap solution behaves as a weak electrolyte, and the formation of micelles by soap depends on various factors, including temperature, pH, and the presence of certain ions.
Which of the following options are correct?a)Micelle formation by soap...
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). On dilution, these colloids revert back to individual ions.
