Chemistry Question on Colligative Properties
The Tyndall effect, associated with colloidal particle is due to:
A
the presence of electrical charge
B
scattering of light
C
absorption of light
D
reflection of light
Answer
scattering of light
Explanation
Solution
Colloidal particles due to their bigger size, scatters the light. Hence, they show Tyndall effect. When the colloidal solution is watched from perpendicular to the light-plane, colloidal particles look like stars in sky.
