Chemistry Question on Classification of Colloids
Using very little soap while washing clothes, does not serve the purpose of cleaning of clothes, because:
A
soap particles remain floating in water as ions.
B
the hydrophobic part of soap is not able to take away grease.
C
the micelles are not formed due to concentration of soap, below its CMC value.
D
colloidal structure of soap in water is completely distributed.
Answer
the micelles are not formed due to concentration of soap, below its CMC value.
Explanation
Solution
The little amount of using soap while washing clothes, does not serve the purpose of cleaning of clothes because the micelles are not formed due to the low concentration of soap as it is below CMC.
So, the correct option is (C): the micelles are not formed due to concentration of soap, below its CMC value.
