A cationic colloidal electrolyte forms micelle at `10^(-4)` M concentration in water. If `1 mm^3` solution contains `10^(12)` micelle structure, then the no. of cations involved in one micelle are:

A

20

B

40

C

60

D

80

Text Solution

Verified by Experts

The correct Answer is:
C
No. of particles of cationic colloidal electrolyte/litre before micelle formation ` = 10^(-4) xx 6 xx 10^(23) = 6 xx 10^(39)`
`therefore` No. of particles of cationic calloidal electrolyte/`mm^3 = 6xx 10^(19) xx 10^(-6) = 6 xx 10^(13)`
Number of micelles formed ` = 10^(12)// mm^3, therefore` Number of cations in one micelle ` = (6 xx 10^(13))/(10^(22)) = 60`
