(b) Filterability
(c) Tyndall effect

CBSE Class IX Science SA 2 (3 Marks)

Answer 1

solution : (Stability) they are very stable
(filterability) particles of solution can pass through filter paper
(tyndal effect) particles of solutions cannot seen
suspension : (Stability)they are unstable
(filterability) they don't pass through filter paper
(tyndal effect) particles of a suspension seen by naked eyes
colloids : (Stability) they are quite stable
(filterability) particles of colloids cannot pass through filter paper
(tyndal effect) particles of colloids can seen by naked eyes
