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

Answer»

`(V_(s))/(V_(c))~~10^(-3)`
`(V_(s))/(V_(c))~~10^(3)`
`(V_(c))/(V_(s))~~1`
`(V_(c))/(V_(s))~~10^(23)`

Solution :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)`
