The volume of a colloidal particle, `V_(c)` as compared to the volume of a solute particle, `V_(s)` in a true solution could be

Options

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

Answer

B

Explanation

Diameters of colloidal particles in a colloidal sol is in the range of 1-1000 nm. Whereas solute particle in a true solution have diameters less than 1 nm.
` therefore (V_(c))/(V_(s))=(4//3pi(10^(3)//2)^(3))/(4//3pi(1//2)^(3))=10^(9)` (maximum)
`therefore V_(c)//V_(s)` could be `10^(3)`
