6. A solution is transparent blue. It is
(a) a suspension
(b) colloid
(c) true solution
(d) both a colloid and a true solution
7. The correct designation representing* the particle size is
(I) (II) (III)
(a) I = true solution II = suspension
III = colloid
(b) I = suspension II = true solution
III = colloid
(c) I = colloid II = suspension
IF! = true solution
(d) I = true solution II = colloid
III = suspension
8. The random zig-zag motion of colloidal particles is called
(a) Tyndall effect (b) ultrafiltration
(c) Brownian motion (d) centrifugation
