Question

Which of the following types of mixtures exhibit the Tyndall effect?
a. solutions
c. colloids
b. suspensions
d. none of the above

Answer 1

C) Colloids

Colloids have small non-dissolved particles that flow around in the mixture. These particles do not settle over time. When a light is shined on colloids the scattering characteristic of the Tyndall effect are visable.
