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

Options

A. `V_(c)/V_(s) approx 10^(-3)`
B. `V_(c)/V_(s) approx 10^3`
C. `V_(c)/V_(s) approx 1`
D. `V_(c)/V_(s) approx 10^(23)`

Answer

B

Explanation

For true solution, the diameter range is 1 to 10 Å and for colloidal solution, diameter range is 10 to 1000 Å.
`(V_(c))/(V_(s))=((4//3)pir_c^(3))/((4//3)pir_s^(3))=((r_c)/(r_s))^(3)=10^(3)`
