The volume of a colloidal particle, V_C cas compared to the volume of a solute particle in a true solution V_S could be

Answer»

`(V_C)/(V_S) ~= 10^3`
`(V_C)/(V_S)~= 10^(-3)`
`(V_C)/(V_S) ~= 10^(23)`
`(V_C)/(V_S) ~= 1`

Solution :The size of a colloidal particle is about 10 TIMES(say r=10) that of SOLUTE particle in a TURES solution. Hence, the volume of a collaoidal particle `(V_C)` is `10^(3)` = 1000 times `(V prop r^3)` that of the solute partice in a true solution `(V_S)`
`therefore V_(C) prop 10^3`
`V_S prop 1`
Hence, `(V_C)/(V_s) ~= 10^3`
