Collidal solution is a heterogeneous solution which contains particle of intermediate size, i.e., (diameter between 1 and 1000 nm) colloidal is not a substance but it is a state of a substance which depends upon the molecular size. Colloidal solutions are intermediate between ture solution and suspensions.

B. `10mmu-1000mmu`
C. `1nm-1000nm`
D. `10^(-5)cm-10^(-7)cm`

Answer

C
