Which of the following is a correct property of a colloidal solution?
The particles scatter a beam of light.
A colloidal solution has particles of intermediate size (1 nm – 1000 nm) that are large enough to scatter a beam of light passing through the solution.
This scattering, the Tyndall effect, is the distinguishing property of colloids and is not shown by true solutions.
Hence, the answer is The particles scatter a beam of light.
