The volume of a colloidal particle Vc as...

The volume of a colloidal particle `V_c` as compared to the volume of a solute particle in a true solution `V_s` could be 

A

`(V_c)/(V_s) = 10^3`

B

`(V_c)/(V_s) = 10^(-3)`

C

`(V_c)/(V_s) = 10^(23)`

D

`(V_c)/(V_s) = 1`

Text Solution

Verified by Experts

The correct Answer is:
A
Size of colloidal particles = 1 to 100 n.m (say = 10 nm)
`V_c = 4/3 pi r^3 = 4/3 pi (10)^(3)`, size of true solution particles = 1 nm
`V_3 = 4/3 pi (1)^(3) , (V_c)/(V_s) = 10^3`
