Answer 1

Answer:

1.

true solutions is the homogeneous mixture

colloidal solution and suspension solutions is heterogeneous

2.

the size of particles of a true solution is less than 1 nm of diameter

the size of particles in a colloidal solution will be larger than that of true solution and smaller than suspension solutions

3.

true solutions is transparent

colloidal solution is translucent

suspension solutions is opaque
