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

Options

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`

Answer

A

Explanation

Size of colloidal particles `=1` to `1000nm` (say `10nm`)
`V_(C)=(4)/(3)pir^(3)=(4)/(3)pi(10)^(3)`
Size of vsolute particle `=1mn`
`V_(S)=(4)/(3)pi(1)^(3)`
`(V_(C))/(V_(S))=((4)/(3)pi(10)^(3))/((4)/(3)pi(1)^(3))=10^(3)`
