ColloidsMediumQuestion 890004

Question

The size range of colloidal particles is:

A
1 nm to 1000 nm (1–1000 nm)
Correct
B
<1 nm (true solution)
C
>1000 nm (suspension)
D
Exactly 100 nm

Correct answer

1 nm to 1000 nm (1–1000 nm)

Explanation

Particle size classification: True solutions (<1 nm, pass through semipermeable membrane). Colloids (1–1000 nm, pass through filter paper but not semipermeable membrane). Suspensions (>1000 nm, do not pass filter paper).
